Abstract
A method and apparatus for cooling a continuously moving strip of asphaltic material includes directing the asphaltic material into a plurality of loops having lengths and widths, spraying an evaporative liquid onto the asphaltic material from spraying means positioned upstream from various ones of the lengths, and evaporating the evaporative liquid immediately downstream from each of the spraying means by causing an array of air jets to impinge on the asphaltic material substantially normally to the lengths.

Apparatus for cooling a continuously moving strip of asphaltic material comprising means for directing said asphaltic material into a plurality of loops having lengths and widths, and a plurality of cooling units, each of said cooling units being associated with one of said loops, each cooling unit comprising:
- a. spraying means positioned to spray evaporative liquid onto the asphaltic material in the loop;
- and
- b. air delivery means positioned immediately downstream from said spraying means and adapted to cause an array of air jets to impinge on the asphaltic material substantially normally thereto to evaporate said evaporative liquid from the asphaltic material in the loop.
A method for cooling a continuously moving strip of asphaltic material comprising subjecting said asphaltic material to a plurality of cooling cycles, each cooling cycle comprising:
- a. spraying evaporative liquid onto said asphaltic material from a means for spraying;
- and
- b. evaporating said evaporative liquid immediately downstream from said means for spraying by causing an array of air jets to impinge on said asphaltic material substantially normally to said asphaltic material.
A method for cooling a continuously moving strip of asphaltic material comprising directing said asphaltic material into a plurality of loops having lengths and widths and subjecting said asphaltic material to a plurality of cooling cycles, each cooling cycle being associated with one of the loops, and each cooling cycle comprising:
- a. spraying evaporative liquid onto the asphaltic material in a loop from a means for spraying;
- and
- b. evaporating said evaporative liquid immediately downstream from said means for spraying by causing an array of air jets to impinge on said asphaltic material substantially normally to said asphaltic material in the loop.
