equipment. The asphalt can be either virgin asphalt blocks or
reclaimed asphalt-containing material such as roofing refuse.
The asphalt particulate is sized from between 1/4" minus
gradient to 2" minus gradient, preferably sized to
approximately 3/4" minus gradient. The particulated asphalt
and crushed roughage then are mixed together to form an
asphalt-aggregate.
The asphalt-aggregate of Gaudio is then mixed with the
third component of his invention which is a solvent. The
solvent additive preferably is varied to correspond to
construction or repair weather temperatures. In warmer
temperatures, a water-based solvent is the preferable solvent
additive. In pavement applications, the water constituent of
the water-based solvent relatively rapidly evaporates from the
cold mix composition after pavement construction or repair
application, to leave a rigid compound capable of withstanding
roadway pressures. In colder temperatures, an oil-based
solvent is preferable to
