The following equipment was chosen by Equipment World editors as the top roadbuilding products of the year.

Sliding seat and console

BOMAG CR 820 W paverBOMAG overhauled the operator platform on its new tracked CR 820 T and wheeled CR 820 W pavers with the company’s Sideview in which both seat and console can swivel out together at four different angles. That gives views of the paver’s side and screed end gates. And through the platform grate, operators can watch the screed’s spreading augers. A 7-inch color screen displays operating functions, gauges, parameters and fault messages. The CR 820 can pave widths of 8 to 20 feet with extension and up to 12 inches thick. The hopper has a 10-ton capacity.


Reduce need for rollers

Dynapac TH E tamper, high-compaction, electric screed

Dynapac says it can achieve 94 percent pre-compaction with the new TH E Series tamper, high-compaction, electric screeds for its highway-class pavers. A hydraulic pressure plate on the back of the screeds helps achieve the higher compaction, which can lead to up to a 50 percent reduction in roller compaction. Operators can adjust the pressure plate’s vibration via the screed remote-control panel or by the main operator station. The screeds come in two models, the V5100 TH E and V6000 TH E, with working widths up to 29.5 feet.


Heavier screed, greater compaction

LeeBoy 8530 asphalt paverLeeBoy’s new tracked 8530 asphalt paver comes standard with the 4,150-pound Legend HD Pro Screed for greater compaction on large jobs, including municipal work, subdivisions, and state and county roads. The paver features a wide, slow conveyor to prevent segregation. The screed also has automatic temperature control. Other features include a high-deck operation station to give operators a better view. The seats swing out and swivel. The hopper holds 9 tons. Max paving depth is 8 inches. Paving widths range from 8 feet to 15 feet 6 inches.

Electrically heated screed

Mauldin 760 Paver

Mauldin made its electrically heated Freedom Screed standard on the new 760 gravity-fed paver. A 12-kilowatt mounted generator delivers heat through six heating elements.

Volvo Construction Equipment designed its new P5110B tracked and P5170B wheeled pavers for heavy commercial and light highway work. The 20-ton pavers run on Volvo’s D6 173-horsepower engine, also used in its L60H to L90H wheel loaders. The tracked model uses on average 3.7 gallons per hour, and the wheeled paver, 3.3 gallons per hour. The engine is also designed to reduce vibrations and produce a low noise level of 79 decibels. The UltiMat160 screed delivers paving widths of 8 to 18 feet with extensions. The hopper has a 12-ton capacity.

Make fewer passes

Case Construction Equipment’s PT240D pneumatic tire roller compactor

Case Construction Equipment’s PT240D pneumatic tire roller is designed to require fewer passes and improve penetration and compaction density. The roller has four tires in front and four in the back with 2-inch tire overlap that gently kneads hot-mix asphalt as it rolls across it. The company says that leads to greater asphalt density and reduces the chance for voids. It is built for sub-base and asphalt compaction on large road and highway projects. Compaction width is 78.2 inches. Operating weight is 21,380 pounds and 52,910 pounds at full ballast.

Change timing belt in 2 hours

Dynapac CO5200 Oscillation RollerDynapac’s CO5200 VI tandem roller features vibration on the front drum and oscillation on the rear. It represents the company’s largest roller, at 11.7 tons and a 77-inch compaction width, to offer oscillation. The drums are made of Hardox 450 steel to reduce wear. The timing belt on the oscillating drum can be replaced in 2 hours instead of the typical two-day process. Operators can switch to only oscillation for such things as bridge decks and joints when gentler compaction is needed. It runs on a 130-horsepower turbo Cummins Tier 4 Final engine.

Simpler ballasting system

HAMM HP 180i pneumatic tire compactorHamm’s HP 180i pneumatic tire compactor is part of the next-generation HP series, to replace the GRW models. The HP 180i has a larger water capacity, designed to last a full day without refill. The ballasting system has been made easier to adjust and to keep weight distributed evenly on each axle. Prefabricated steel or concrete ballast bodies can be inserted and removed with a forklift. The HP 180i ranges in operating weight from 8 to 18 metric tons and has a compacting width of 72 inches. It is runs on a 74.2-horsepower Deutz Tier 4 Final engine.

Dual-drum oscillation

Sakai SW994ND roller compactor

With the SW994ND, Sakai has introduced its fourth compactor with dual-drum oscillation. The 84-inch-wide double-drum roller can handle dense-grade hot-mix as well as stone matrix asphalt mixes for highways. Sakai’s oscillating models are gear-driven, so no belts need to be replaced. The dual-drum oscillation enables the compactor to more efficiently achieve required density and surface textures, the company says. Both drums can also be switched to vibration. The SW994ND has an operating weight of 31,570 pounds.

High-frequency vibration
