At Cleveland Hopkins airport they are shown milling a taxi-way. The first pass they milled was up to 9″ deep 72” wide and was milling an average of 36′ per minute. The second pass being a little harder aggregate they milled at 8.5″ depth and averaged 32′ per minute. They were very pleased with the production of the machine.

One unique feature is this W210 is designed with 2 engines and the onboard computer systems can determine the engine output for simple maneuvering and traveling. It may only require one engine in use; however as the demand for HP increases for milling applications the computer will put the second engine into action. This is a considerable fuel savings instead of running one higher HP engine at higher rpm’s all the time. Fuel savings can range up to 20-30% over the conventional drive train. The engine can run in 3 different work ranges manually. Kokosing opted to run it in the medium setting, which is 1800 rpm. Economy setting is 1600 rpm and high setting is 2100 rpm. They felt they got their best production at that setting.

Wirtgen’s exclusive Level Pro Multi-Plex non contact averaging system was utilized during the asphalt removal for more accuracy for profilograph requirements on smoothness asphalt paving. For more on the W210 and Level-Pro and for Kokosing Construction, see the attached link.

Shelly and Sands, Inc is putting to good use the latest in technology from The Wirtgen Group’s Vogele paver division in Mannheim, Germany with the purchase of 2 new Vogele Vision series pavers model 5200-02 rubber track pavers, one for the Columbus Division and one for the Akron Division.

They also decided to incorporate the latest in technology for the Columbus based machine with two Niveltronics Big Ski averaging systems. This system in built in house at Vogele and allows you to reference a bigger foot print for meeting the tougher IRI smoothness profilagraph requirements set today by ODOT. The Niveltronics system also comes standard with dual grade and slope controls already incorporated in the screed operator consoles.

Another important choice when choosing the Vogele Vision Series paver was the auto lube system that takes care daily of the feed and material handling system on board the machine.

Most important in making the buying decision was the support that they have received from The McLean Company and the co-involvement of Vogele’s service, engineering and management teams in handling all issues.

LINCOLNTON, N.C. – At CONEXPO, VT LeeBoy, Inc. introduced its 9000 Asphalt Paver, a 33,000-pound paver featuring a maneuverable, rubber tire design and an 8-foot electrically-heated screed system.

This high production rubber tire asphalt paver is powered by a 173-HP CAT Tier 3 diesel engine, which provides the power to push larger tandem axle trucks with ease. The engine is transversely mounted, which allows for better ground level access and cooling efficiency. A fume ventilation system vents asphalt vapors away from the operator and screed area. Two Series 90 variable displacement pumps drive paver functions. An easily raised hood covers the low profile engine and side grating is easily removed to provide access to the engine compartment.

The LeeBoy 9000 operator stations are designed for maximum comfort and ease of operation. It includes dual hydraulic slide-out operator stations to enhance fore and aft visibility with fully equipped consoles that incorporate CAN Bus system design and digital gauges for monitoring paver functions and diagnostics. Paver steering is by Plus 1 control architecture with touch pads.

The 9000 rubber tired paver provides excellent maneuverability, ground speed, ride quality and traction. The tire system is comprised of two large heavy-duty low pressure rear 19” x 29.5” drive tires. The 12 x 22 inch solid rubber front tandem steering bogie wheels oscillate to improve mat quality by overriding roadbed irregularities.

The material handling system on a 9000 paver begins with an 11-ton receiving hopper with heavy-duty, hydraulic radius hopper wings and high strength plastic flashing to prevent material spillage. Dual 18” heavy-duty slat bar and roller chain conveyors feed the 16” diameter hardened cast steel augers that push asphalt to the screed. The auger assembly can be hydraulically raised and lowered, which is helpful in the loading and unloading process. Standard sonic feed sensors control the augers. The operator has independent left and right control of the conveyor system and material flow gates. Manual tunnel extensions are available to keep mix away from the drive tire.

The 9000 paver has a heavy-duty electrically heated and vibrating Legend Screed System that extends hydraulically from 8- to 15.5-feet. An onboard 20 Kw generator electrically heats the main screed and the front-mounted extensions. LeeBoy’s exclusive heat element replacement system makes replacing heating components easy. Adjustable screed extensions feature a 9 degree slope.

A two-speed motor with single reduction planetary torque hub allows the 9000 paver to travel at speeds up to 13 mph. The 9000 paver can pave at speeds up to 250 fpm.

Fluid capacities are among the largest for this size paver with an 82-gallon fuel tank, 86-gallon hydraulic oil capacity and 15-gallon citrus washdown tank.

Part of a new line of midsized mills, the W 120 F is a high-performance cold milling machine with a drum width of 48 inches (120 cm), ideal for removing complete asphalt courses with a milling depth of 0 to 12.6 inches (0 to 320 mm). Its engine output is 304 hp, and it replaces the W 1200 F/T in the product line.

The W 120 F has a hydraulic swinging track for flush cutting, and features front-end loading of reclaimed asphalt pavement (RAP) via a two-part conveyor system. The machine is available in a tracked version but can be ordered in a wheeled version.

The optional Flexible Cutter System (FCS) permits the use of different milling drums with working widths of up to 48 in. and a variety of line spacings. And the W 120 F will be equipped with the new Wirtgen Level Pro® leveling system.

Wirtgen also will exhibit the new WR 2000 XL recycler/stabilizer, with a 94-in. cutting drum and 425 hp engine.

Shelly and Sands uses the oscillatory technology from Hamm Compaction to help themselves out of a tough application on US RT 23 in Chillicothe, Ohio. The job requirements were two asphalt 12mm lifts over joint repaired concrete that carried smoothness and density requirements. This is a problem for all contractors in Ohio (see Flexible Pavements article link) http://www.flexiblepavements.org/images/techbullcrackseal.pdf

Traditional vibratory rollers were first used to compact the material. Joint repair bumps would occur so it was determined by Ed Morrison of Shelly and Sands QC department to try using the new Hamm oscillatory roller technology along with old technology of the pneumatic tired roller. Both worked very well in getting rid of the bump reoccurrence.
