Better Roads 50 Top Rollouts for 2006
New Products
We sort through hundreds of 2006 new product introductions to identify 50 that have the most significance to highway and bridge professionals.
How We Made Our Choices
In surveys, focus groups, and face-to-face meetings at industry events, when we ask readers how we can best help them keep track of changes in the products and services they use to manage, maintain, and build North America’s roads and bridges, almost everyone wants an annual short list of the really important stuff. No wonder. The sheer volume of introductions is overwhelming. Better Roads covers well over 600 products each year in our new product columns and Bid List features.
So each year, our staff reviews all the product introductions we’ve covered for the past year (our Top Rollouts "year" actually runs from the November 2005 issue through the November 2006 issue) to pick out 50 that we believe are worth further review. Our priorities are new concept products, which are rare, new series/new generation products in categories that relate to the road and bridge industry, and other rollouts which serve our readers’ interests by increasing supplier competition for their business.
Inevitably, we omit deserving products, either because we just didn’t understand the significance of the product or because the announcing company did not communicate what was special about the product, or both. In either case, we apologize in advance for these omissions.
Gomaco
Planning the pour
Gomaco added an important new dimension to its Gomaco Smoothness Indicator technology this year. Originally introduced in 2005 to provide smoothness readings for wet or cured concrete and asphalt slabs, it can now be used to analyze grade accuracy before paving. GSITools is a new software application that utilizes data gathered with the GSI before paving takes place to provide a grade accuracy analysis of the subgrade and/or the stringline. The software can provide an estimated material yield for the project, and pinpoint high and low spots in the subgrade.
Volvo Construction Equipment
Operator-designed motor grader line
Volvo dramatically re-engineered its motor grader line in 2006, bringing forth dozens of innovations based on input from grader operators and owners. The new seven-model G900 Series brings increased power, fuel efficiency, and grading sophistication to the grader category.
Mechanical improvement starts with Tier 3 engines that produce more power than previous engines yet accomplish better fuel efficiency due to torque curves that better match power demands.
The G900 series’ most distinct new mechanical feature is Volvo’s new powershift transmission, a unique direct-drive system that can be operated manually or as an automatic. It was developed in-house to achieve a level of shifting smoothness not possible with previous technology. In addition to silky smooth shifts, it has a "shuttle shift" capability, allowing the operator to directly shift between forward and reverse in either direction without stopping, clutching, or pausing. The shuttle shift feature is designed to make the machine more productive when working on short runs and in tight spaces.
The standard transmission is an eight-forward-speed model, and Volvo offers an 11-forward-speed version — the industry’s first — as an option. The latter has a higher top speed (30.8 miles per hour vs. 28 miles per hour) and more precise gearing for variable power demands.
Among other notable features, both six-wheel-drive models in the series feature front-wheel-drive-only Creep modes that can inch forward as slowly as 0.1 miles per hour without stalling. And all models got a dramatically smaller turning radius than the previous series offered, even though all wheelbases were extended for more stability and blade down force. The turning radius was achieved by increasing frame articulation and wheel lean.
Davidson Traffic Control Products/Filtrona Extrusion
Channelizing system
Davidson Traffic Control Products, a division of Filtrona Extrusion, won ATSSA’s innovation award this year for their new Interstate Grade FG 300 Curb System designed for use on high-speed interstates. The median separation system provides channelization of traffic on freeways, tollways, city streets, and at-grade rail-highway crossings. The radial rib structure provides more than 10,000 pounds of crush strength.
The curb system includes Flexi-Guide FG 300 EFX channelizer posts that are made of polyurethane combined with a unique alloy of engineering polymers to provide durability, low maintenance, and good visibility. The posts install using a quick-pin system, have a self-righting T-shaped design, support a 4- by 22-inch or 3- by 39-inch vertical panel, and are available in bright colors such as florescent orange and florescent yellow-lime green.
Vogele
Sophisticated compact paver
Wirtgen subsidiary Vogele introduced an innovative compact asphalt paver in 2006 that combines highway class technology with a design that lets it drive through an opening less than 4-feet wide, pave within 2 inches of barriers, and drive in a footprint of 113 inches. The new Vogele Super 700 features an electrically heated screed, a 57-horsepower diesel engine, and an 8kW tractor-mounted generator for screed heating and lighting. When high production rates are not paramount, it can be operated at reduced rpm in Vogele’s unique ECO Mode to reduce fuel consumption, noise, and wear.
Hopper capacity for the Super 700 is 5.5 tons. Unlike other hydraulically operated hoppers, the Super 700 is equipped with hinges to allow many material feed configurations. The feed system has two augers driven independently of the conveyor for optimal flow. The augers and conveyors are reversible.
Vogele says the new machine is capable of paving a 6-inch lift at a laydown rate of 220 tons per hour. It can pave at up to 98 feet per minute and has a top transport speed of 2.2 miles per hour.
Cimline
Cracksealing’s next step
Cimline continued to tackle the issue of pavement cracks in 2006 with the introduction of their second generation Magma Series melter/applicator. The unit seals cracks in pavement, helping to extend pavement life. Generation II technology incorporates a new hose design, new wand construction, and improved external pump design for the 110-, 230-, and 410-gallon models. The technology behind the lightweight Superflex III heated hose minimizes kinks and flex damage with a full 0.75-inch inner diameter and small outer diameter. The wand design features replaceable aluminum pipe and ball-valve construction, and provides easy and safe recirculation back to the sealant tank when not in use. Magmas come standard with on-board spare parts kits and self-priming burners, as well as a fume-reduction system and noise-insulated engine enclosure.
SignCad Systems
Automated work-zone design/management
SignCad Systems introduced their new ConeZone, a fully integrated and automated system for work-zone design and management, at ATSSA’s Traffic Expo in February. The system uses its patented Dynamic Arrangement Engine to select devices and configurations from state-approved lists and standards, and then automatically places them with GPS into the work zones so they can be properly installed and mapped. This concept provides state DOTs and municipalities with a development tool to design and install safer work zones.
Using additional SignCad modules, ConeZone becomes a Web-based suite of integrated applications that allows agencies throughout the state to have their traffic control plans automatically written and coordinated with other work-zone activities. In addition, the system runs simulations to test for mobility and safety; generates work orders for the DOT, municipalities, and contractors; keeps work-zone standards and approved devices current for all users via its Web repository; automatically documents work-zone activity including permits, inspections, and incidents via Web interface; and inventories, tracks, and manages all objects and devices in the field.
Topcon
‘Revolutionary’ new satellite receiver
Topcon pioneered new ground in satellite positioning systems this year with the rollout of its GR-3 system and its RTK GNSS satellite receiver. The GR-3 system is the first designed to capture signals from all three satellite positioning systems — including the planned Galileo system from the European Union — and the just-unveiled RTK GNSS receiver is the first receiver for all existing and planned satellite constellations. For construction users of positioning systems, the new technology promises better signal reception in traditionally difficult locations, such as among high-rise buildings or in canyons.
The new receiver has also been designed for ruggedness and durability: it can withstand a fall from a 2-meter range pole onto concrete and has an extensive warranty. It has 72 universal channels and can track up to 36 satellites simultaneously.
Humboldt
Electronic density gauge
Humboldt introduced an alternative to the traditional gauge with their new non-nuclear Electronic Density Gauge. The gauge is used for determining the physical properties of compacted soils used in roadbeds and foundations. The portable, battery-powered instrument measures and displays wet and dry density, gravimetric moisture content, and percent compaction. Humboldt says it delivers performance and measurement results highly comparable to those yielded by traditional methods, including nuclear gauge, sand-cone, and oven drying.
John Deere
New generation of excavators
John Deere introduced six models in its D-series excavator line in 2006, ranging from the 54,244-pound 240D LC to the 185,520-pound 850D LC. Along with Tier 3 engines, the series makeover includes totally redesigned cabs with dramatic increases in sight lines, more legroom, shorter pilot controls, and fully adjustable suspension seats. Hydraulic flow has been increased for more digging power and precise control, and daily operating costs have been reduced with a series of designed-in features, including a 5,000-hour service interval on the hydraulic system.
Caterpillar
Joystick-operated motor graders
Caterpillar shook up decades of motor grader design this year with the introduction of its joystick-operated M-series. In the new family of graders, the traditional row of levers for controlling drawbar, circle, and moldboard functions are gone, replaced by excavator-like joysticks that allow the operator to manipulate the DCM with fingertip ease from a relaxed sitting position.
Along with the new controls Cat re-engineered the cabs for comfort and excellent views of the blade and blade edges, and design of the drawbar, circle, and moldboard to dramatically simplify maintenance. Also new is a variable horsepower scheme that increases horsepower in 5-horsepower increments as the machine progresses to the next gear; the small increments deliver a smooth power curve that allows the machine to carry heavy loads while downshifting.
Cat also improved its all-wheel-drive models in the M-series by adding a second hydraulic pump to power the front wheels; the change increases front-wheel torque by 42% and allows independent control of the front wheels. Cat has applied for more than 100 patents relating to the new graders.
Volvo Construction Equipment
Next-generation skid-steer loaders
Three years after introducing its first skid-steer loader line, Volvo rolled out five new B-series models that have been upgraded or redesigned completely in 33 areas. New features include a choice of foot and hand mechanical controls or hand-operated hydraulic pilot controls — the only machines in the industry to offer such a choice. A new seat bar provides an ergonomic armrest and control lever positions fall naturally to hand, improving efficiency and reducing fatigue.
The hydraulic pilot control system uses two joysticks, with the right hand controlling loader functions and the left hand controlling drive functions. The new cabs are larger, and boast improved lines of sight. Isolation mounts reduce vibration and noise.
Along with a host of structural improvements, hydraulic and driveline systems have been modified to improve performance and increase top travel speeds. The three largest models offer an optional high-flow hydraulic system to operate high-performance attachments like snow blowers and planers.
Many of the heavy-duty features of the original machines are being carried over, including the one-piece welded mainframes and cast iron axle housings. B-series machines range in size from the 1,350-pound rated MC60B to the 2,250-pound-rated MC110B.
Power Curber
Paver attachment digs post holes
Power Curber introduced one of the most unique new products of 2006 with an attachment for its 5700-Super-B slipform paver that automates the installation of steel cable barriers in highway medians. This post-hole digger attachment allows the machine to dig pier holes up to 34-inches deep, then slipform concrete foundations for steel cable posts. Power Curber says the process is much faster than current manual methods and produces a concrete foundation that prevents grass from growing around the posts, simplifying grass-cutting maintenance. Steel cable is gaining favor as a safety barrier in six states and 27 others are also installing it, according to the company.
The post-hole digger attachment mounts on the left rear of the 5700-Super-B and is powered with the machine’s auger conveyor circuit. The auger for the post-hole digger operates inside a cylinder. It moves the dirt upward into a hinged chute, catching the material before it hits the ground. The hinged chute allows the material to be dumped out of the way of the slipform application and eliminates the need for a crew member to move the dirt manually.
After the holes are dug, the 5700-Super-B slipforms the foundation, filling the holes with concrete as it passes over them. The machine’s vibrators consolidate and strengthen the concrete, eliminating voids, then a crew member inserts a tube into the pier. A steel post is inserted into each tube and the wire rope is strung between the posts.
W.R. Meadows
Joint-sealing compound
W.R. Meadows introduced a new Hi-Spec polymeric hot-applied sealant for portland cement concrete this year. The single-component, joint-sealing compound is formulated with a blend of 100% virgin polymer, asphalt plasticizers, and inert reinforcing fillers. It produces a hot-pour joint sealant with excellent bonding properties and high resiliency, ductility, and resistance to degradation from weathering. It will not become brittle at low temperatures and will not flow or migrate from the joint at temperatures up to 140 degrees F, according to the company. Hi-Spec is recommended for large-scale sealing of joints and cracks in portland cement concrete and asphalt concrete pavements. It is available in 50-pound containers and 55-pound cartons.
Liebherr
New generation loaders
Liebherr introduced its "Generation 6" wheel loaders in 2006 with the rollout of the L 566 and L 580. The 259-horsepower L 566 weighs 50,570 pounds; it has a 5.25-cubic-yard standard bucket capacity and a tipping load of 24,750 pounds. The 272-horsepower L 580 weighs 54,185 pounds; it has a 6.5-cubic-yard standard bucket and a tipping load rating of 39,850 pounds. Both feature Tier 3 engines with more power than the models they replace. Their cabs are 28% larger than the previous models and feature single-part laminated front windscreens.
Contech
Underground water detention system
Contech stepped up to the plate, or drain, this year with the introduction of their new Optimizer, an underground detention technology system engineered to stabilize and manage stormwater runoff. Contech says the system contains innovative flow-control devices that use a pressure head to begin immediately discharging at the maximum allowable rate, reducing the required storage volume. The result is a smaller, more economical corrugated metal pipe detention system.
The process lowers project installation costs due to less excavation and backfill necessary on the smaller-size. Less pipe is also installed, which is ideal for tight sites where larger systems won’t work.
Stoltz
Spreads dry additives dust free
Stoltz, a division of Stoltzfus Spreaders, introduced its new Site Spreader A2 last summer touting it as a solution for dust-free pneumatic filling of cement, lime, fly ash, and other dry bulk materials in soil stabilization applications. The Site Spreader A2 combines a simplified control system, a high-flow relief vent, and a breakaway spreading auger for easy operation and high reliability. It uses two 10-inch-diameter augers in place of the 30-inch-wide drag chain in Stoltz’ original high volume model. The company says high capacity hydraulic motors and deep reduction gearboxes guarantee the product will not bind in the hopper.
Sakai
‘Balanced’ static roller
While most of the focus of the asphalt roller market has been on vibratory models for the past half-decade or so, Sakai’s most innovative product rollout of 2006 was a static roller. Called by Sakai a "balanced" three-wheel roller, the new R2H-1 is an 83-inch-wide machine designed to compact thin lifts, city streets built over fragile infrastructure, and other pavement situations in which vibration isn’t appropriate. Unlike old-time three-wheel static machines, Sakai says the wheels of the R2H-1 have the same diameter and provide equal compactive force per linear inch; the machine develops 365 pounds of force per linear inch along its 83-inch rolling width. All three wheels are driven, for optimum traction and minimal shoving, and water ballast can be used to increase output forces.
Aspen Aerials
Moves easily on bridges
Early in 2006, Aspen Aerials rolled out a bridge inspection unit that is uniquely maneuverable around bridges. It has a horizontal reach of 62 feet and needs no outriggers. Its unique features include a telescoping fourth boom and a 180-degree rotating platform that enables operators to get into tight areas behind deep beams. A microprocessor control system shows unit operation and individual function performance on a color display. A second rotating turntable has an automatic leveling system that adjusts for bridge slopes while providing smooth platform movement.
Liebherr
Faster hydraulic coupler system
Liebherr completed the North American rollout of its unique Likufix automatic coupler system for excavators in 2006. The system incorporates a quick coupler with an automatic hydraulic coupling system, and it allows the operator to change hydraulic attachments in seconds without leaving the cab. It uses two patented connecting components that are attached to the existing Liebherr quick-coupler adapter and a hydraulic attachment such as a hammer or grapple.
National Asphalt Paving Association
Training for paving crews
We’ve never given a Top Rollout award to an association before, but? NAPA’s Tool Box Talks are special. These short presentations for training paving crews in the field are, first of all, commercial products that sell for $155 per module. They are also developed by the very companies that want to use them, providing non-commercial instruction for safe, efficient, quality paving. The topics include the truck exchange, longitudinal joint construction, MTV exchange, rolling procedures, and compaction forces. Each kit includes a large-format flip chart presentation and five pocket-size trainee booklets.
Unique Paving Materials
Concrete patching material
A new concrete patching material from Unique Paving Materials hit the highways this year. This specially designed material patches, repairs, and restores worn or damaged concrete surfaces and structures. CPM is a high-strength, rapid-developing, commercial-grade concrete patch that offers resistance to chlorides and acids. The company says the material can withstand high freeze-thaw conditions, allows minimal chloride penetration, and has high compressive and shear/bond strength without the need for an additional bonding agent. A 2-inch layer of material begins to set up within 20 minutes of use, and the area can be reopened to traffic in as little as 45 minutes to an hour. For repairs deeper than 6 inches, a second layer can be applied after 30 minutes. The repaired surface is ready for paint after 24 hours.
Terex Roadbuilding
Improved paving performance
Terex Roadbuilding substantially upgraded the paving mode of the Terex|Cedarapids CR662RM Road Mix this year. The innovative machine won a Top Rollout award last year for its two-way versatility: it can be switched from a material transfer vehicle to a paver in a matter of hours. This year, the company increased the sophistication of the paver mode. The machine now features new outboard-drive spreading augers and a new-generation Remix System. Two 5-foot-long auger sections deliver material to the left and right sections of the screed. Each auger section has its own speed control so operators can independently adjust material flow to either side of the screed. The augers back up to each other, so there is no separation in the center. The new design eliminates the center gearbox drive and the need for reversing augers, reducing occurrences of centerline segregation, according to the company.
Along with the new augers, the Remix System has been enhanced with two sets of two counter-rotating augers with interleafing shafts that draw down material from all areas of the hopper and aggressively reblend the asphalt. The company says the system virtually eliminates both material segregation and thermal segregation.
Quixote Transportation Safety
Impact attenuator
Quixote Transporation Safety introduced the Quest impact attenuator this year, which consists of a series of two-beam fender panels supported by diaphragms with a trigger mechanism at the nose. When hit, it releases a front assembly to absorb the energy of the impact. The system measures only 18-feet, 10-inches long and 24-inches wide. During head-on impacts, the system telescopes rearward to absorb the energy of impact and brings the errant vehicle to a controlled stop; when impacted from the side, the system is capable of redirecting vehicles at angles up to 20 degrees and is 25% reusable after 0-degree impacts. Refurbishment typically involves replacing a damaged unit, with repairs done off site.
Geophysical Survey Systems
Air-launched horn antenna for bridge evaluation
In 2006, a collaborative effort between Geophysical Survey Systems and the Maine Department of Transportation found a 2 GHz air-launched horn antenna to be an effective tool for providing accurate assessments of the condition of bridge decks. The air-launched horn antenna and a 1.5 GHz ground-coupled antenna were used to evaluate the condition of an asphalt overlaid bridge deck located in Lewiston, Maine. GPR data lines were acquired at 2-foot intervals by walking the ground-coupled antenna system and by driving a vehicle with the air-launched horn antenna system.
The data was processed with GSSI’s Radan software program using the Bridge Assessment Module. The results were used to produce color-coded deterioration maps of the bridge deck. Results from both antennas in comparison demonstrated excellent correlation. The deterioration maps from both antennas compared with visual data obtained from top-side and bottom-side visual inspections exhibited excellent correlation.
The Maine DOT further confirmed correlation by hammer sounding and, finally, by opening the bridge deck to expose the actual areas of deterioration.
Bomag
New milling machines debut
Competition in the milling machine market place got a little stiffer in 2006 as Bomag introduced two new utility-size machines to the North American market. Both feature centrally mounted cutting drums for precise milling close to walls, curbs, and other obstructions. The BM1000/30 has a standard 39.6-inch cutting width while the BM1300-30 cuts 51.4-inches wide. Both machines use a 275-horsepower engine and direct mechanical drive for the cutting drum; they can mill to depths of 12.6 inches.
Bomag says the centrally mounted cutting drum eliminates the need to move the right rear track away from the cut line, preserving the machine’s overall balance. The drum position also allows the use of much shorter take-off belts than competing models, resulting in lower maintenance costs, according to the company. Other features include an "over-the-cut" operator position with a seat that can slide out over the right edge of the machine to give the operator an excellent view of the drum’s leading edge and the line or curb to be followed.
Foundation Mechanics
Pavement data collection vehicle
This year, Foundation Mechanics combined ground penetrating radar and falling weight deflectometer data collection and storage, and made it all available in one vehicle. The company integrated the RoadScan GPR system from Geophysical Survey Systems into its trucks to collect and store pavement thickness information at each FWD test location. The average difference in thickness between the physical core and the GPR thickness measurement is less than 4%. The GPR system is fully FCC certified.
Mack
The next step in work trucks
Mack introduced the next generation of its Granite and Granite Axle Back truck series this year. The new models feature the all-new MackPower MP7 engine, an 11-liter block available in six horsepower ratings between 325 and 405 horsepower. Hallmarks of the new engine are said to be a significant improvement in fuel economy and "tremendous low-end torque response." The new trucks are built on the 116-inch BBC Mack Cornerstone chassis. Their cabs have an extra 4 inches of depth for more leg and belly room, and to allow a seat recline angle of more than 20 degrees. Also new: a wrap-around, cockpit style dash; one-piece windshield; and a broadly adjustable steering column with driver foot-pedal controls suspended, rather than floor-mounted. The pedal arrangement means the driver’s heel never has to leave the floor when switching between fuel and brake pedals.
Bobcat
Four-wheel-drive tool carrier
Bobcat continued to apply the tool carrier concept to new and different base machines in 2006 with the introduction of the 2300 four-wheel-drive utility vehicle last summer. The new machine can mow, sweep, and move materials with its one-of-a-kind RapidLink attachment system. The system’s attachment arm lifts loads up to 500 pounds as high as 2 feet. The vehicle can be equipped with five specially designed Bobcat attachments, including a bucket, mower, pallet fork, snow blade, and whisker push broom. Users can operate and change attachments from the cab with an easy-to-operate joystick control.
The 2300 is powered by a 20-horsepower diesel engine, and offers an adjustable steering column and driver’s seat. A power cargo dump box with an 800-pound bed load capacity comes standard. For added towing and rear attachment capabilities, a standard 2-inch receiver hitch is included on the rear of the vehicle.
Terex Roadbuilding
New mid-range concrete pavers
Terex Roadbuilding brought new competition to the mid-range concrete paver market in 2006 with the introduction of the two-model Terex|CMI SF3500B Series. Both models are said to feature massive frame section construction to deliver minimal deflection over their entire 12- to 33-foot paving widths. They also feature the Hydra-Mation grade control system used on other Terex models. Terex says the control system has just two moving parts and delivers 0.10-mm precision for elevation, steering, and cross-slope control.
Caterpillar
Mid-size wheel loader upgrades
Caterpillar didn’t just describe the difference between its four new H-series mid-size wheel loaders and the previous G-series, the company treated the trade press to side-by-side demonstrations that showed the new machines are much faster, thanks to an advantage in horsepower and to a new hydraulic system which make the host machine much more efficient when performing multiple tasks simultaneously.
Ranging in size from the 216-horsepower 950H to the 307-horsepower 972H, the new machines all feature load-sensing hydraulics and new engines that meet Tier III emissions requirements and also deliver more power, fuel economy, and cost efficiency. To further enhance fuel efficiency, the engines employ Cat’s new idle management software. This provides four idle settings for the machine: hibernate (for fuel efficiency during long periods of idle); work; warm up (for cold weather start-ups); and low voltage mode.
Also new on the mid-size loaders are electro-hydraulic implement controls which feature soft detents and which, with the load sensing system, allow operators to simultaneously lift and tilt the bucket for better bucket control and less spillage.
Champion
Big-thinking compact graders
Champion Motor Graders made waves in compact motor grader circles with the introduction of its new C80 C and C86 C models, calling them compact graders that think like big graders. The all-wheel-drive C86 C is the company’s largest grader, at 15,500 pounds; the C80 C is its tandem counterpart.
The redesign of these two machines starts with the front axle, which now provides 50 degrees of steering angle left and right, compared to 35 degrees in previous models. Champion says this gives the new machines an industry-best turning radius — a straight-frame turning radius of 25 feet, and an articulated turning radius of 19 feet. The axle also now features spherical bearings at all moving points to provide a longer service life, and 22 inches of ground clearance — 6 inches more than the previous models and enough to go where the big graders go, according to the company.
Also new is a 21-inch moldboard, tallest in the category, according to Champion. A new blade lift arrangement increases featherability by increasing the blade lift stance 14 inches to a full 4-feet across, widest in its class according to Champion. The company also replaced its traditional ball joint for the articulation cylinders and engineered a clevis-style mounting for optimum strength. The cylinders are now mounted on spherical bearings for increased service life.
Barrier Systems
Portable steel work-zone barrier
The BarrierGuard 800 steel safety barrier from Barrier Systems was introduced at ATSSA’s Traffic Expo in February. The barrier can be used in work zones or as a permanent installation. As much as 600 feet of barrier can be delivered to a jobsite in one truck load. According to the manufacturer, a crew of three can install up to 1,000 feet per hour because of its QuickMount connection system, which uses only one bolt. The barrier has very low deflection and vehicle exit angles following impact, and can be moved easily within the work zone.
Caterpillar
10-foot pavers advance
Caterpillar has incorporated new Tier 3 engines in its high-production 10-foot pavers, the wheel-type AP-1000D and the track-mounted AP1055D. Along with the new 224 net-horsepower turbodiesel engine, the 10-foot pavers get a new high-capacity cooling system for working in high ambient temperatures. Fuel economy has been improved and sound levels have been reduced, according to Cat.
Designed to pave Interstates, highways, subdivisions, and airports, Cat’s 1000-series pavers feature dual operating stations that rotate into four different positions for optimum visibility, and a proprietary material handling system that Cat claims is the industry’s most advanced. The 6.1-cubic meter hopper has a 10-foot, 7-inch-wide truck entry width. The hopper includes power dumping controlled from the operator stations, with heavy-duty flashing to prevent spillage. The machine controller is used to calibrate and precisely control the augers and feeders. Left and right augers are controlled independently, as are the left and right feeders, eliminating the need for feeder gates.
Both machines are available with the Extend-A-Mat or the AS-2301 screed; electric heating systems are available as options on both screeds.
MetroCount USA
Intersection timing analysis units
MetroCount USA introduced their new two-channel Timing Analysis Roadside units for detailed analysis of signalized intersections, pedestrian crossings, and rail crossings. Installed at the crossings and interfaced with the signals, the units record traffic data on one channel and signal changes on the other. The MC5711 and MC5712 gather time-stamped axle data for every vehicle on one channel using two air tubes spaced 3 feet apart. The other channel simultaneously logs the signal phases. Used in conjunction with Traffic Executive’s MCReport software, you can analyze the speed, vehicle type, headway, gap, and more of every vehicle entering the intersection, all relative to the signal phases.
HIL-Tech
In-pavement LED lighting system
HIL-Tech shed some light on road safety in 2006 with the introduction of their new linear, encapsulated LED lighting system that can be used for pedestrian crossings or to increase road safety and efficiencies by creating highly visible in-pavement markings, symbols, and signs. The LEDline is visible in just about any weather and can help guide motorists at night and in severe weather conditions. It can be induction powered and connected so there is no hard wiring, or DC powered for barriers and signs. The 15.75-inch-long by 1.2-inch-wide by 0.75-inch-deep solid plastic unit comes in a semi-directional or omni-directional format. According to the company, the unit is snowplowable, weather resistant, corrosion proof, submersible, vandal resistant, and versatile.
Gomaco
Programmable width changes
Concrete pavers looking for a choice in variable-width paving solutions got one in 2006 as Gomaco announced that its V2 dual-mold system is now available with an optional auto-width adjustment package to provide sensored control of on-the-go paving width changes. The new feature allows a proportional control to change the width of the mold while paving to produce a tapered slab. Stringline is set to follow the desired tapered slab, and sensors on the paver use the string line to control cylinders for extending the frame and side-shifting the mold. The operator engages the automatic system with the switch of a button as the machine approaches a width transition.
Energy Absorption Systems/Quixote Transportation Safety
Trailer-mounted attenuator
Energy Absorption Systems, a Quixote Transportation Safety company, introduced their new trailer-mounted SST Safe-Stop Truck Mounted Attenuator in 2006. The attenuator requires minimal modification to host vehicles and allows quick, simple attachment, which results in low installation and operating costs, as well as increased truck fleet operating flexibility. The attenuator’s length from the back of the host vehicle is less than 20 feet. An added feature is anti-rotational dampeners designed to lock the attenuator in place during an angled impact to maximize effectiveness and minimize impacting vehicles from gating into a work zone or adjacent lanes. The dampeners also protect the host truck’s frame by spreading the load of the impacting force and provide maximum protection for work crews, the impacting driver, adjacent drivers, and the host vehicle.
LeeBoy
High-content compact paver
With some of the large paver manufacturers starting to offer smaller models, LeeBoy has been very active in defending its turf for the past few years. In 2006, they introduced the 8510 conveyor paver to fill a niche between the 8500 and 8515 commercial-class pavers. The 8510 features 12-inch-diameter casted augers and a 7.5-ton hopper constructed of heavy-duty 0.375-inch steel with large radius hopper wings for enhanced material flow. Standard features include hydraulic operating controls and dual-lever joystick steering from both sides of the paver. The 8510 has a full electronic control system, an upgrade from the 8500’s manual cable-type drive system. Power comes from a 74-horsepower engine. An 8- to 15-foot Legend Screed System with dual vibrators is standard equipment, and there is a choice of propane or electric heat systems.
Caterpillar
Reclaimer gets more power, productivity
Engineering advances in the popular 500-horsepower category of road reclaimers/soil stabilizers continued in 2006 with Caterpillar rolling out the RM-500 Rotary Mixer to replace its RM350B. The new 540-horsepower model has a Tier 3 engine with 8% more horsepower than the RM-350B. It also has upgrades in traction, weight balance, serviceability, versatility, and productivity, according to Cat. Key features include full-time all-wheel drive, large tires with aggressive tread, two speed ranges (work and transport), and electronic gear selection. The all-wheel-drive system features two independent variable-displacement propel pumps that supply balanced oil flow to the front and rear drive motors.
Three rotor styles are available. The universal rotor is designed to handle both asphalt reclamation and soil stabilization; it has a 16-inch maximum cutting depth. The application-specific soil rotor has a 20-inch maximum depth; and a combination rotor handles both soil stabilization and light asphalt reclamation.
Cimline
Cracksealing for the economy minded
Cimline expanded its family of cracksealing solutions this year with the introduction of a new-from-the-ground-up economy model. The new 150-gallon Matrix 1500 melter/applicator combines features from Cimline’s established Magma series with pumping technology developed by sister company Garlock Equipment, a manufacturer of roofing products. The stand-alone, economical cracksealer is designed for municipalities and contractors. It has an oil-jacketed tank and recirculation feature for fast heat-up and even sealant temperatures. Digital controls allow the operator to start the 22-horsepower engine and step away while the machine heats up and maintains sealant temperatures (to within 1 degree F of the target temperature). Its angled burner chamber provides 250,000 Btu of heating and a direct-drive agitator in the tank helps maintain temperature and prevent scalding.
The unit has a low, 54-inch loading height for safety and it comes standard with a 20-foot SuperFlex III electrically heated sealing hose. Options include an on-board air compressor and heat lance for one-pass sequence of crack cleaning, heating, and sealing.
Volvo Construction Equipment
Wheel-mounted compact excavator
Volvo brought an interesting dimension to the increasingly popular compact excavator category in 2006 with the introduction of a wheel-mounted version of its 5.5-metric-ton short-swing-radius EC55B excavator. With a top speed of more than 18 miles per hour, the new EW55B combines the mobility of a backhoe loader with the productivity of an excavator. The 52-horsepower unit weighs 11,552 pounds and has a digging depth of 11 feet, 2 inches. It has a hydrostatic-driven, four-wheel-drive chassis with wet disc brakes. The front axle has power-assisted steering and a center oscillating pivot to assist in conforming to road and terrain conditions. Two oscillation lock cylinders keep the front axle fixed when the machine is digging.
John Deere
Unique 2-cubic-yard loader
John Deere rolled out the J-series version of its 2-cubic-yard loader last winter, praising it as heavier, more powerful, more fuel efficient, and easier to maintain than the model it replaces. The company said it also rates as the fastest, most powerful (in terms of breakout force), and most maneuverable machine in the 2-yard loader class.
The 98-horsepower machine features steering wheels in the rear along with the loader’s traditional articulation. The rear turning feature allows the machine to turn tighter than conventional machines, and it also dramatically enhances stability when turning with a load. The rear wheels also oscillate, improving ride and traction on rough surfaces.
Revamped for 2006 with a Tier 3 engine, the 344J now boasts 17,310 pounds of breakout force, by far the highest in the 2-yard loader class and similar to some machines in the 2.5-yard class. The boost in breakout force comes from an improved load-sensing, closed-center hydraulic system that delivers power on demand.
Other features of the 344J include a hydrostatic drive train that can propel the unit to a top speed of 19 miles per hour — tops in the class, according to Deere. It also has more reach than leading competitors, with a dump clearance of just over 9 feet, 4 inches. Also making truck loading faster and easier is Deere’s return-to-dig feature. The redesigned cab features more window area, walk-though doors, and low-effort controls.
Road Systems
Larger, higher barrier system
Road Systems addressed the problem of larger, higher-center-of-gravity vehicles on the road today with the introduction of their new MGS Barrier System. The system has a top rail height of 31 inches rather than 27.625 inches and a blockout of 12 inches rather than 8 inches. This added block width improves performance by raising the rail height by 3 inches or more as the post is deflected, allowing the barrier to contain and redirect the higher center-of-gravity vehicles. Also, rail splices occur mid-span between posts rather than at the post. This helps prevent wheel snag at the base of the post.
Case Construction Equipment
New wheel loader series
Case kept pace with advances in the mid-size wheel loader category this year, rolling out E-series versions of its 183-horsepower 721 (3-cubic yard standard bucket) and 213-horsepower 821 (3.8-cubic yard standard bucket). In addition to Tier 3 engines, the new machines get a new cab design, and improved service and maintenance features. Both models also feature ride control as standard equipment to enhance material retention and reduce shock to operator and machine when traversing rough surfaces. Ride Control can be set for full-time or in auto mode when roading above 3 miles per hour.
Cab upgrades include lower noise levels, better vision, more space, and adjustable steering column, seat, arm rests, and control placement. The Tier 3 engine can be managed with three power curves — max, standard, and economy power. The machines also have four work modes — max, standard, economy, and auto. Service checks require no tools and can be done from the ground; remote drains are provided for coolant, engine oil, and hydraulic oil.
Stanley LaBounty
Design doubles blade life
Stanley LaBounty rolled out a new line of shears this year featuring an automated blade lubrication system that is said to significantly reduce maintenance and enhance shearing performance. The company says in extensive field testing, the MSD Saber-Lube Series had double the blade life of previous models and cut build-up welding time on the affected jaw areas in half. There was at least two weeks less downtime per year with the new system, and usable cutting power was increased up to 8% by reducing blade friction.
Laserline
Wing plow guidance laser
Laserline’s new GL3000C Wing Plow Guidance Laser made its mark this year, literally. It uses an ultra-high-visibility laser to establish wing-plow trailing edge location before the snowplow gets there. The laser spot impacts on the road/snow surface ahead of the truck and shows the driver where the wing plow trailing edge will be. The laser guide was designed specifically for snowplow guidance and the rigorous environment that the equipment is subjected to.
3M
All-weather reflective tape/paint
3M introduced a new line of all-weather markings this year, featuring their new wet reflective technology that provides reflectivity on roadways under wet or dry conditions. The Stamark High Performance Wet Reflective Tape Series 380WR ES is a durable marking with extended season application advantages, designed for long-term road presence and well suited for new surfaces. The All Weather Paint is a matched component system consisting of high-build waterborne paint and both wet and dry reflective elements. According to the company, the reflective elements maintain their reflectivity in a downpour.
New Holland
New backhoe-loader series
New Holland marked the 40th anniversary of its first backhoe loader this year with the introduction of the new five-model B-Series. The series includes the B95 and B95TC (Tool Carrier) in the 14-foot size class, and the B95LS (Long Reach), B110 and B115 in the 15-foot class. The series uses 4.4-liter turbo-charged engines rated from 95 to 110 gross horsepower. The new machines are said to deliver the most horsepower in their classes resulting in class-best breakout forces for loader productivity and fast boom swings for backhoe productivity. They provide excellent reach at dump height to make grapple and bucket work easier, according to New Holland. Other hallmarks include high-capacity, fast-response hydraulics, and superb visibility due to a narrow backhoe boom and a higher operator station than competing machines offer.
Hamm Compaction
High-end utility rollers
Hamm Compaction, a division of Wirtgen America, used 2006 to roll out two compact articulated asphalt rollers that offer vibration in both the front and rear drums. The 1.6-ton HD 8 VV and the 1.73-ton HD 10C VV can be operated with vibration in the front drum only, in both drums, or in static mode. The HD 8 VV has a 31.5-inch drum width; the HD 10C VV, 39 inches. Hamm says the double-drum compaction capability gives the two new models high production capabilities in a small package for commercial or roadbuilding applications.
Both models share an 83.5-inch-long platform and have a total height of 84.8 inches. They also share a unique cantilevered drum suspension system which uses a single support leg on each drum — right leg only in the front, left leg only in the rear. This design permits compaction right up against obstructions such as walls or curbs, according to Hamm.
Zero Gravity Tools
One-person blade changes
Zero Gravity Tools introduced one of the year’s most innovative products with its BH-1000 system which makes it easy for one person to change grader blades safely and efficiently. The tool mounts on the mold board and takes all of the lifting out of lowering the old blade and raising the new one into position. It works with all standard graders.
