Application No. 09/072,190
prevent freezing of the solvent constituent within the
composition and mixing equipment used to carry the solvent to
the asphalt-aggregate for preparation of the end composition.
Gaudio discloses that in warmer temperatures, the
preferred solvent is comprised of a water-based emulsion type
rejuvenator, such as that known by the trade name "Reclaimite
[sic, Reclamite]" by Witco Oil Co. of Oildale, Calif.
According to Gaudio at column 5, lines 4-19, "Reclaimite" is a
blend of oils suspended in water to form an emulsion capable
of dispersing the oils to lubricate the product to which it is
applied. With water as the carrier of these oils, the water
is left to evaporate, leaving the oils to be absorbed by the
subject product, thereby causing softening, reconditioning and
rejuvenating of the subject asphalt product. Thus, after
mixing the water-based solvent with the asphalt-aggregate, the
final asphalt composition of the present invention can be
stockpiled for thirty to sixty days to allow the water portion
of the emulsion to evaporate.
