LeeBoy
Two heavy-duty commercial pavers

LeeBoy expanded its line of asphalt pavers in 2003 with the introduction of the 8816, a 25,000-pound, 130-horsepower, track-mounted paver designed for road and large commercial applications. The machine employs LeeBoy’s vibrating, heated Legend Screed system and a 10-ton receiving hopper. Standard features include independent auger and conveyor control, patented under-auger cut-off plates, and 14-inch variable-speed augers. The screed is hydraulically extendible from 8 to 15 feet. Operator features include dual operator stations, electric-over-hydraulic controls, and proportional electronic steering.

Last year, the company re-engineered its 8515 paver, retaining its maneuverability and size while adding big paver enhancements that reduce operating costs and increase productivity for users. New from the ground up, the 8815 has a heavier track assembly and undercarriage, and a hydraulically raised hopper bed that provides maintenance access to the undercarriage and tracks. The 74-horsepower tractor has a two-speed hydrostatic drive and carries a 7.5-ton hopper that features heavy-duty radius hopper wings that enhance the flow of material into its dual 36-inch slat-feeding conveyors. The screed is a beefed up Legend system.

Caterpillar
High-production commercial paver

Cat introduced its rubber-track-mounted AP-655C 8-foot paver in 2003 as a high production machine capable of paving large parking lots by day and streets and highways by night. Weighing 40,800 pounds, the machine features a 174-horsepower turbo-charged engine, Cat’s Mobil-trac undercarriage, and an advanced material handling system. The material handling system uses a controller to independently control left and right augers and left and right feeders, eliminating the need for feeder gates and enhancing the machines productivity, according to Cat. The paver has two operating stations, each with a fully equipped console, and each capable of swinging out to the side for better visibility. The cooling system features an electronically controlled, variable-speed, on-demand fan to reduce engine power requirements and noise.

Ingersoll-Rand
Paves driveways and parking lots

Ingersoll-Rand rolled out its new Blaw-Knox 3120 commercial paver early last year. It features the Liberty Screed and a new tractor with a low-slung, 8-ton hopper bed and dual independent auger and conveyor systems. The 15,800-pound machine is powered by an 87-horsepower diesel. The Liberty screed has front-mounted hydraulic extensions, a four-burner propane heating system, and the ability to adjust both the angle of attack and the height of the extensions. It paves in 8- to 15-foot widths.

The 3120 offers the lowest hopper bed in its class, according to the company, and its curved design is said to improve material flow in clean up. Under-auger cut-off doors allow the operator to control material flow to the main screed and extensions.

Terex
New commercial paving screeds

Terex Roadbuilding recently introduced its new VersaScreed series of 8- and 10-foot screeds designed for paving subdivisions, county roads, parking lots, and other commercial applications. The series uses 24-inch-wide main and 8-inch extension screed bottoms for consistent mat texture across the entire paving width, and the wedge-shaped design of the extensions is said to shed asphalt when narrowing paving widths, eliminating trapping and shoveling.

The 8-foot VersaScreed offers variable paving widths from 8- to 13-feet wide; the 10-foot model provides infinitely variable widths from 10- to 17-feet wide. Optional bolt-on extensions expand paving widths to 16 and 20 feet, respectively.

Other features include variable hydraulic vibration up to 3,000 vibrations per minute, and the same tipping-frame technology found on Terex’s Stretch Series screeds, formerly sold under the Cedarapids brand. This design is said to eliminate the need for wear strips and shims, and to better maintain settings between the main frame and extensions.

Vogele
New paver line debuts

Wirtgen subsidiary Vogele America has rolled out an updated five-model line of asphalt pavers designed and built in Chambersburg, Pennsylvania. The line includes two commercial class pavers and one utility class unit. The 110-horsepower 2111W (formerly the 780 WB) and the 150-horsepower 2116W (formerly the 880 WB) are 8-foot rubber-tire models, and the 152-horsepower 2116T (formerly the 880 RTB) is an 8-foot rubber-track machine. The commercial-class 2116W weighs 32,000 pounds while the 2116T comes in at about 30,000 pounds. At 27,000 pounds, the utility class 2111W has enough heft and horsepower for many commercial paving applications.

With the new paver models come new 10-foot and 8-foot screeds. The 10-foot HR500D and 8-foot HR400D are diesel-heat, hydraulic-extendible models with rear-mount extensions. New this year is the HR500E, an electric-heat version of the 400D, and the all-new HR400E, an 8-foot electric-heat screed with front-mounted extensions.

Bomag
Mid-size paver gets makeover

Since acquiring the ProPaver line last year, Bomag has reintroduced the ProPaver 813RT with some enhancements under the Bomag brand. The unit now features an 80-horsepower turbo diesel engine which Bomag says lets it cope with heavy workloads. The company also touts the paver’s load-sensing hydraulic system as an exclusive feature that reduces fuel consumption by delivering power only when needed, yet allows the 813RT to push feeder trucks.

Paving widths from 4 to 14 feet are standard on the 813RT; with optional bolt-on extensions it can pave up to 16-feet wide. Hydraulically controlled screed extensions let the operator change widths on the go between 8 and 14 feet. Optional ditch plates allow paving widths as narrow as 16 inches.

Roadtec
High-powered for reliability

The 155-horsepower RP-155 is Roadtec’s 8-foot, commercial class rubber-track paver. The company says it achieves reliability and productivity advantages by coupling the large turbo diesel with an oversized cooling system. The unit also features a newly designed undercarriage and an improved material handling system. It is recommended for work in all types of subgrades and paving applications, and its narrow shipping width makes it a non-permitted load, for quick movement between job locations.

The RP150 is the wheeled counterpart to the RP-155. It features the same engine, screed, material handling system, and shipping dimensions, and features a short wheelbase that allows it to achieve a 30-inch turning radius for work in tight areas.

Terex
Versatile, high-horsepower performer

The new Terex/Cedarapids 300 Tier 2 Series 8-foot commercial pavers got a 27% increase in power — to 165 horsepower — when the company upgraded to Tier 2 engines. The series includes a choice of rubber-track or rubber-tire models, and a choice of screeds — the 8-foot diesel Fastach, the 8-foot electric VersaScreed, or the diesel or electric Stretch 16.

Terex claims the 352 rubber-tire paver is the most productive model in its class, with a 366-foot-per-minute paving speed and production rates as high as 758 tons per hour. The 362 rubber-track paver can pave at 205 feet per minute and has the same production capacities as the 352.

The revamped line now has an improved cooling system, produces less noise, and can pave all day without refueling.

Ingersoll-Rand
Improved material flow

Also new last year from Ingersoll-Rand was the 73-horsepower, 15,500-pound 3020 utility/commercial paver, which comes standard with IR’s V-3 Xtend-a-Screed. It paves 8- to 13-feet wide, using screed-under-screed technology, and its extensions have been redesigned for more torsional stiffness and precision placement. The 3020 has an 8-ton hopper and dual independent auger and conveyors systems. It has the lowest hopper bed in its class — 21.5 inches — to minimize truck bed and hitch interference during the transfer of asphalt to the paver. Curved hopper wings improve material flow and enhance clean up.

LeeBoy
Enhanced paving on grades

LeeBoy has also upgraded its 37-horsepower, 10,000-pound 1000D tilt-hopper paver. It uses an 8- to 13-foot heated and vibrating Legend screed that has hydraulic extensions mounted in front of the main screed. The low-deck unit can be built on steel tracks or rubber tires. LeeBoy says its newly designed 5.5-ton receiving hopper raises higher than any other paver in its class to enhance paving on steeper grades.
