New Asphalt Paving Equipment: September

AsphaltPro takes you into the homestretch of the paving season with a product gallery focused on the new technology and equipment that assists contractors in the paving and pavement preservation/pavement maintenance arenas. One of the most recent products introduced to the marketplace came from Roadtec of Chattanooga in its road widener, the BF 400.

The Roadwidener/Side Paver BF 400 from Roadtec is designed for road widening, shoulder work, maintenance and repairs of roads—a multi-talented machine for driveways, road extensions, roadside banks and trenches. All types of soil, gravel and asphalt can be placed because the conveyor belt is made with a special structure that is heat resistant up to 356oF. The surface of the road functions as a reference guide for the material placement. Screed slope, material height and width can be adjusted hydraulically.

The operator of the BF 400 is positioned on the side of the machine where all hydraulic levers are in reach. The material hopper is wide enough to receive all sizes of trucks, according to the manufacturer. Hydraulically extendable truck push rollers adjust to the different truck bodies. The extendable screed has a working width up to 6.5 feet. There are three manual screed extensions. Depending on the layer thickness, the laydown speed is between 49 and 164 feet per minute.

The BF 400 weighs 4.1 tons and has a laydown capacity of 400 TPH, according to the manufacturer. It’s fitted with a water cooled 3-cylinder Kubota diesel engine and a Danfoss hydraulic system. The manufacturer recommends to push and steer the roadwidener with a wheel loader, telehandler, tractor or similar piece of equipment. It also has a new option with a truck hitch connection.

New From Atlas Copco

The F1000 pavers from Atlas Copco, Commerce City, Colorado, feature new auger and tunnel systems. Here’s the scoop.

Atlas Copco’s F1000W wheeled and F1000T tracked 10-foot pavers allow contractors to equip the units with either a center auger drive system or outboard auger drive system for a variety of applications. The pavers also can be equipped with Atlas Copco’s new tunnel extension system.

The center drive auger system features a 6-inch wide chain box and 17-inch diameter flights to ensure uniform material flow and minimize centerline segregation. The outboard auger drive system is ideal for paving wide roads with normal speed paving applications, according to the manufacturer. The drive box for the left and right auger are positioned at the outer edges, which helps minimize centerline segregation. Dynapac’s exclusive auger-conveyor feed-control system is designed to ensure a continuous material flow. The system uses four ultrasonic sensors that measure paving material and automatically adjust conveyors and augers to optimize material flow. The system is designed to eliminate segregation and deliver a constant head of material.

The 10-foot pavers can also include a hydraulic tunnel extension system along with the center drive auger system. The 22-inch wide hydraulic tunnel extension will automatically retract when screed extensions begin to retract to prevent collision. The hydraulic tunnel reduces excess head of material in the tunnel area and prevents asphalt from entering into track components.

The material flows through the Carlson front- or rear-mounted screed to construct flawless mats. A tractor-mounted 34-kW generator heats the screed’s full working width, which is as wide as 28 feet with the Carlson EZ R-2 screed. The front extension screed is ideal for paving parking lots, county roads and city streets because contractors can change its width quickly to suit to the project’s demands. The robust rear extension screed extends to 28 feet wide for use on large paving projects, including highways, interstates and airports.

New From BOMAG

The rubber track Cedarapids CR662RM RoadMix from BOMAG, Ridgeway, South Carolina, features a new 260 horsepower (191 kW) Tier 4 Final Cummins diesel engine. With a 21-PSI fully loaded ground contact pressure, the CR662RM is designed to be used on all paving lifts, including the base, to eliminate material and thermal segregation.

Replacing the traditional in-hopper slat delivery system, the improved Remix Anti-Segregation System delivery augers now feature hard-faced back sides to increase wear life. The two sets of two variable-pitch, counter-rotating augers uniformly draw down material from inside the hopper to remix 100 percent of the asphalt to combat segregation at the jobsite. Auger pitch spacing transitions from 10 inches at the front of the hopper to 12 inches at the rear to channel material to the transfer conveyor or screed. This design results in throughput capacities in excess of 600 TPH whether equipped as a paver or MTV.

In less than four hours, the efficient crew can remove the rear conveyor assembly used for transferring material from the tractor and replace it with the screed assembly. “If necessary, a contractor could pave with the RoadMix in the morning and use it as an MTV in the afternoon,” Henry Polk said. He’s the product marketing manager—paving products for BOMAG. “This is one machine that will rarely sit in a contractor’s yard.”

The Cedarapids CR662RM RoadMix now comes standard with three years of complimentary BOMAG Telematic service. BOMAG Telematic monitors machine vitals, delivers text and email alerts to key personnel, reminds the dealer and service technicians when scheduled maintenance tasks are due, and offers a number of productivity reports to help maximize machine use. “Even at full load,” Polk added, “Telematic is showing us that the CR662RM uses only an average of 5 gallons per hour.”

Patented Smartrac™ technology extends the CR662RM RoadMix’s track life, warranted for three years/3,000 hours. Oscillating bogie wheel assemblies combine with the system’s frictionally driven rubber tracks to automatically apply the correct tension to the track, regardless of traveling in forward or reverse. The self-tensioning system is designed to not over-tension the track.

When equipped as an MTV, the CR662RM’s 30-inch wide conveyor offers a discharge height of 73.2 to 115.8 inches for non-contact paving and swivels 55 degrees left or right of center for off-set paving. For mainline paving, the CR662RM can be equipped with either the Stretch 20 or Fastach 10 screed and is capable of paving at widths reaching up to 30 feet. Two independently controlled, variable-speed outboard drive motors eliminate the need for the spread auger center gearbox drive to reduce the occurrence of centerline segregation.

New From Caterpillar

Caterpillar Inc. announces the availability of the PM620 and PM622 cold planers as of first quarter 2016. The half-lane milling machines are designed to perform controlled full-depth removal of asphalt and concrete pavements in a single pass. Operating weight for the PM620 is approximately 73,260 pounds and the PM622 is approximately 74,580 pounds. Both are powered by a Cat^® C18 ACERT^™ engine, a turbocharged, 6-cylinder diesel engine that provides 630 horsepower of gross power. The C18 engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards. The engine is iso-mounted to reduce vibration and increase operator comfort. The automatic engine speed control feature allows the engine to optimize output to match the load, reducing excessive fuel consumption and wear on the engine. The turbocharged air-to-air aftercooling system provides high horsepower with increased response-time while keeping exhaust temperatures low. The cooling system provides cool intake air in order to maximize fuel efficiency and minimize emissions. An on-demand variable speed fan draws ambient air from the top of the engine hood and through the cooling package, keeping the engine compartment cool. Heated air exits from the rear of the machine, directed away from the operator’s station for greater operator comfort.

The PM620 and PM622 utilize a four-post design. The leg posts feature an auto-leveling function that provides smooth height adjustment without stepping.

The machines are fully hydrostatically, driven by two variable displacement propel pumps supplying oil to variable displacement motors on each track. Drive motors are piston-type and designed to automatically control displacement to provide maximum torque for work or greater speed for moving around the job site. A propel lever/steering joystick provides infinite control of the travel speed within the range. The machines have a propel system with a diagonal cross flow design for traction. The pumps drive opposing track motors, front to back and side to side.

Track tension automatically adjusts to ensure optimum operation. Track assemblies are 70.4 inches long, 12 inches wide and feature replaceable, bolt on polyurethane track pads for long service life.

Four-mode steering is standard. An electronic control module processes inputs from the sensors on the front and rear tracks along with input from the steering selector controls. It provides precise simultaneous track movement in the crab and coordinated steering modes and automatically realigns the rear tracks to center when the front-tracks-only steering mode is selected. In the coordinated mode, the inside turning radius is 6 feet 5 inches.

The rotor drive system features a dry clutch driving a planetary gear reducer. The clutch is coupled to the engine and is hydraulically actuated by the keypad controls on the operator’s console. Three cutting speeds are available to match the best rotor RPM and torque with the job site conditions, and are controlled electronically from the keypad on the operator’s control console.

The PM620 is equipped with a 79-inch-wide rotor and the PM622 is equipped with an 88-inch-wide rotor. The maximum cutting depth is 13 inches. The rotor is equipped with durable three-piece, quick release tool holders and carbide-tipped cutting bits arranged in a chevron pattern for maximum breakout force.

The quick release conical tool holders feature a tapered fit, maintaining tightness in the holder base. The mandrel features large, replaceable, carbide-faced loading paddles. Triple-tree cutting bit placements on rotor end cutters provides optimum bit spacing to clean up loose material.

The PM620 and PM622 can be equipped with integrated Cat Grade Control. The 2D-capable/3D-ready grade and slope system automatically controls rotor depth and cross slope to a preset cutting depth, and can be enhanced for full 3D control with the addition of optional equipment.

Sonic grade control sensors can be easily positioned on each side and provide a consistent accuracy to ± 1/8 inch. The collecting conveyor is driven by a high-torque hydraulic motor.

A standard water spray system lubricates the conveyor belt and helps control dust. A centrifugal pump supplies water to spray nozzles in the cutting chamber. The nozzles focus water spray in a flat fan pattern to the rotor for better cooling of cutting bits. The 898-gallon water tank can be filled from standard wide fill openings on the top of the machine or the standard ground level port at the rear of the machine. There is also an optional side fill port. This enables adding water while the machine is operating. An optional water transfer pump is available to facilitate additional filling options. An additional water spray system can be fitted as an option for greater lubrication, cooling and dust reduction during heavy-duty applications. This system includes an additional water pump, a second spray bar located in the rotor chamber housing, and extra spray nozzles on the collecting conveyor.

The hydraulically controlled front loading conveyor features height adjustment for raise and lower and two cylinders for a 60 degree swing to the left and right of center that can be controlled from the operator’s station or at two ground level control stations. It is equipped with upper aluminum covers. The loading conveyor can also be hydraulically folded downwards for transportation.

The seamless loading conveyor belt features 1.25-inch-high cleats and is 33.5 inches wide. It offers long service life and excellent control of fine particles. Variable belt speed provides adjustable control of the loading conveyor.

An optional dust abatement system is available.

New From Vögele

The new Super 2000-3i asphalt paver from Vögele—introduced to North America at World of Asphalt 2016—refines the productive features of its predecessor Vision paver. In 2016, the 10-foot tracked Super 2000-3i replaces the Vision 5200-2i, and is the first of a line that will supplant the Vision series. The new line introduces Vögele Dash-3 technology and its ErgoPlus 3 operating system to a highway-class paver specially suited for North American use. It features a basic width of 10 feet and a maximum paving width of 28 feet. It has a top placement rate of 1,540 TPH. The tracked Super 2000-3i is designed primarily for use in highway construction and large-scale commercial applications. Let’s take a look.

Three main components define the power unit of the Super 2000-3i: its liquid-cooled diesel engine, a splitter gear box flanged directly to the engine, and a large cooler assembly.

• 6-cylinder Cummins QSB6.7-C250 engine rated at 250 horsepower
• Tier 4 final
• Fuel-saving ECO mode is sufficient for many applications. Even in ECO mode, the Super 2000-3i still has a full 234 hp at its disposal, while the machine generates less noise when running at just 1,700 rpm.
• Its fuel tank holds 100 gallons.

The Super 2000-3i features an innovative and reliable drive concept for accurate tracking, according to the manufacturer. All drive components, including the three-phase generator, are supplied from the central splitter gear box. High-traction crawler tracks convert drive power into forward motion.

A large cooler assembly ensures that the power unit always delivers its full output. With innovative air routing and a variable-speed fan, temperatures are continually maintained within the optimum range, extending the service life of both the diesel engine and the hydraulic oil.

Because all hydraulic elements are supplied with hydraulic oil directly from the splitter gearbox, all pumps and valves are combined in one spot that is easily accessible for maintenance work. Even the generator for screed heating is flanged directly onto the splitter gearbox.

The Super 2000-3i comes with the latest version of Vögele’s operating system, the ErgoPlus 3, which has been enhanced with a number of new ergonomic and functional features. With its new mounting system, the paver operator’s console can be shifted easily between the right and left sides of the operator’s stand. In addition, it now has a large color display that ensures good readability even in poor lighting conditions. On the ErgoPlus 3 console, all push-buttons are easily identifiable by touch even when wearing work gloves, according to the manufacturer. Vögele’s Touch and Work principle means that once a button is pressed, the work begins. Functions are executed directly, without the need to confirm.

For this new highway class paver, the Super 2000-3i can be combined with the VF 600, the VR 600 and the AB 600 TV extending screeds. Electric screed heating is standard on the Super 2000-3i. Typical heat-up time is 20 minutes. The ErgoPlus 3 screed operating consoles have been completely redesigned. With ErgoPlus 3, the screed operator has the paving process at his or her fingertips. Also, the main paving functions of the screed can be controlled using one of the two handy screed remote controls for each side of the paver for the VF 600 and VR 600 screeds. Intuitive operation is possible thanks to self-explanatory and language-neutral symbols. The remote controls can be securely stowed in the holders on the main screed, or on the ends of the screed extensions. The holders are magnetic, meaning that the remote controls are easy to grab at any time.

Niveltronic Plus, the exclusive Vögele system for automatic grade and slope control, was developed based on many years of experience in grade and slope control technology. This fully integrated system is adapted to the machine technology of the Super series pavers. All wiring and connections, for instance, are integrated into the tractor and screed. A large and practical selection of sensors permit versatile use of the Niveltronic Plus system. Whether for parking lots, traffic circles or highways, Vögele offers a sensor for every job site situation. Sensors can be changed quickly and easily, for Niveltronic Plus automatically detects which sensor is connected, thus simplifying the configuration.
