ABSTRACT:
The use of impact force to cause an impression to be transferred to an asphalt road surface in a repetitive manner to form a series of depressions. The use of hydraulic, pneumatic and gravity drop as power sources are discussed. Imprint plates having single impression or a plurality of impressions are disclosed. Various shapes for the resulting depressions are explained including a shape that matches current milled depressions. Several methods of installing the series are discussed including stationary stamping, where the machine is paused during stamping, continuous stamping and continuous machine movement with imprint plate pause relative to the surface under treatment. The latter discloses a methodology wherein the imprint plate is transferred rearward on the transport vehicle at a pace equal to the advance of the transport vehicle. Various gauging means are explained to ensure that the resulting depressions are within predetermined parameters which prevent overstamping and understamping. Multiple stamping, where a plurality of impacts are utilized for each resulting depression are explained. Installations having a continuous series and having a skip pattern incorporated therein are explained.
