ABSTRACT:
A method and apparatus for cooling a continuously moving strip of asphaltic material includes directing the asphaltic material into a plurality of loops, spraying an evaporative liquid onto the asphaltic material, evaporating the evaporative liquid by causing an array of air jets to impinge on the asphaltic material subtantially normally to the asphaltic material, sensing the surface moisture of the asphaltic material subsequent to one or more of the loops, and modifying the flow of evaporative liquid sprayed in one or more of the loops in response to the sensed surface moisture.
