Process for heating an asphalt surface

摘要

A process for continuously heating an asphalt surface is described. The process comprises moving a heater over the asphalt surface in successive forward and backward directions. The forward stroke of the heater is effected over a second distance and the backward stroke of the heater is effected over a first distance. The ratio of the second distance to the first distance is in the range of from about 0.10 to about 0.90. Preferably, the heater comprises at least two independent heaters arranged in series.
