High-frequency, high-amplitude compactors — available in three models — feature SMART drum technology. Eight amplitude settings automatically adjust to the highest frequency for that amplitude selection, enabling use of lower amplitudes with higher frequency on thinner lifts and higher amplitude with lower frequency on thicker lifts and stiffer materials. This flexibility serves the function of two compactors in one. The vibration system automatically adjusts vibration frequency for both drums to the design frequency for the given amplitude.

The new model AP-1000D high-production, 10-foot wheel-type asphalt paver features a Cat C7 engine incorporating ACERT technology; dual swing-out operator stations that can be rotated into four different positions; a hydrostatic propel system that provides three propel modes; and a high-capacity cooling package. The material-handling system uses independent feeder and auger controls. The hopper has a 12.2-metric-ton capacity and includes power dumping controlled from the operator stations.

Cimline
Magma melter/applicator compressors in 110-, 230- and 410-gallon capacities are designed for high-volume, high-production jobs. Crack cleaning and crack sealing are performed in a one-pass operation with heavy-duty compressors that output 100 psi. Oil in the inner wall of a jacketed tank is heated with a burner and an agitator keeps the melted sealant flowable. A recirculation feature ensures uniform sealant temperature, and a convection system draws asphalt fumes back into the burner exhaust.

Terex Roadbuilding
The 50,800-pound CR662RM RoadMix material transfer vehicle (MTV) features rubber tracks that spread the vehicle load over a broad surface, reducing ground pressure so it can work on base and top courses. Terex says the CR662RM, with augers in the receiving hopper, is the first and only MTV to reblend 100 percent of the asphalt. When the unit is not needed as an MTV, the rear conveyor assembly can be removed and replaced with any Terex ¦ Cedarapids screed, allowing it to be used as a paver.

Hamm/Wirtgen
Asphalt compactors to be displayed range from the 13-ton, 78-inch-wide, double-drum HD O120V oscillation roller to the company's smallest unit, the HD 10, with an operating weight of 5,690 pounds and drum width of 39 inches. The HD O120V reportedly is the largest compactor in North America to use exclusive oscillation technology that works hot-mix asphalt from side to side. At the other end of the scale, the double-drum vibrating HD 10 is intended for small projects such as driveways.

Trail King
Advantage Series Live Bottom asphalt trailer increases payload by more than 2,000 pounds in a lightweight, modular design without compromising strength, says the manufacturer. Sixty-degree sloped walls reduce load segregation during transport and eliminate bridging problems. A heat- and oil-resistant two-ply rubber continuous belt moves the entire load to the rear for discharge. The 36-inch belt, attached to patented steel slats, moves via a self-lubricating double-pitch roller chain on steel tracks.

Roadtec
New SP-200 asphalt spray paver lets contractors spray asphalt cement or emulsion (tack) directly in front of the asphalt mix before it is laid for NovaChip applications or traditional paving. Spraying the tack seconds before asphalt is laid provides a strong bond between existing surface and new pavement. The gravity-fed paver has a heated 2,100-gallon asphalt cement/emulsion tank and three rows of spray nozzles. Flow rate can be controlled by an onboard microprocessor. The SP-200 eliminates the need for separate tack trucks.

The new WolfPac 4100 is a 40-inch-wide, double-drum-drive asphalt roller facilitates compaction of base, binder and finish coats in confined areas. An electro-hydraulic circuit combined with a custom-designed manifold allows the operator to direct vibration to front, rear or both drums. With 4,O00 pounds of impact per drum, the roller is ideal for driveways, parking lots and more. Other features include centerpoint articulation, short wheelbase, high curb and minimum wall clearance, and pressurized water system with gravity-feed back-up. Ergonomic advantages include vibration isolation, adjustable safety seat and tilted steering wheel.
