摘要:
A road maintenance machine is provided with a heater assembly mounted on a general purpose chassis which is adapted for selectively attaching various road working devices. The heater assembly includes multiple rows of high temperature burner units each having means for burning fuel and projecting the generated heat downward against the road surface. The rows are spaced apart to allow the top of the surface to partially cool between burner rows as the heat penetrates the pavement in order to maintain the surface temperature below its flash point but high enough to achieve sufficient heat penetration to soften the pavement material to a significant depth. Heat shields and exhaust hoods are provided between the rows of burners to confine and direct the heat and combustion products. The chassis is provided with an adjustable hydraulic mechanism to which an asphalt planer, a scarifier assembly or a grooving cylinder may be attached to work the softened pavement material. An elevator is mounted at the rear of the machine to clear the roadway of planed material. An oscillating screen may be connected to the machine behind the scarifier assembly to smooth the worked surface. Methods are described for asphalt heating, asphalt planing, asphalt scarifying and asphalt grooving using the road maintenance machine.

Disclosed is an apparatus and a method capable of forming the anti-slip groove in a variety of shapes without cutting concrete or asphalt pavements unlike the conventional cutting technology, with making use of a non-cutting type of pressurizing rotator (130) under the condition of predetermined temperature and pressure being maintained in such a manner that the pressurizing rotator is mounted to a lower portion of a grooving vehicle. The forming plate (132) is integrally mounted to a radial outer surface of the main body (131) by welding. A plurality of peaks (135) are formed on a surface of the forming plate (132), the peaks (135) being corresponding with a shape of the anti-slip groove to be formed on roadway. Alternatively, a plurality of peaks can be directly formed on a radial outer surface of the main body (131).

Methods, compositions and systems for prolonging the lives of transportation surfaces, including pavement, runways, bridges and parking structures include chemically protecting the transportation surfaces. Chemical protection may be accompanied by physical alteration of the transportation surface, which may enhance one or both of a microtexture and a macrotexture of the transportation surface.

The invention relates to a device for reconditioning the ground area of an arena in a riding hall or in an open riding course, which the device comprises a chassis which spans the breath of the ground area and can be moved lengthwise backwards and forwards. The chassis comprises vertically adjustable tools for preparing and leveling the ground area while the chassis is moving, with a device for dampening the ground area from a low level.

An apparatus for leveling and conditioning baseball infields and the like includes a scarifier, pulverizer, drag, and roller, all mounted on a common frame. The frame and at least some of the implements may be adjusted to adjust or disable the scarifier, pulverizer, and drag individually. The apparatus may be pulled by a small garden tractor.
