ABSTRACT:
In a roadway surface reconditioning apparatus, for example, a scarifier for use with an asphalt or like bituminous roadway surface, a number of heaters of the luminous wall type are employed to direct large quantities of radiant heat downwardly towards the surface for softening it while travelling along the roadway. These heaters consist basically of porous fire bricks through which an air/propane mixture passes and on the surface of which it burns. Each heater also has porous side walls that project closer to the roadway surface than the main bricks and are supplied with air for forming a downward curtain of air to inhibit sideways escape of heat from the region beneath the heater. The heaters are assembled in banks that are spaced apart from each other in the direction of travel. This spacing can be adjusted. Each pair of adjacent banks is bridged by heat deflectors that help to provide heat soak areas between the heater banks. The apparatus also includes a novel scarifying assembly with increased adjustability of the scarifying depth of the teeth.
