The invention relates to liquid compositions that include an aqueous
asphalt mixture and polyurethane dispersion. The polyurethane dispersion
includes a polyurethane that is based on an aliphatic polyol backbone
based on polytetramethyl ethlene glycol and/or polycaprolactone. The
aqueous asphalt mixture in the liquid composition generally constitutes a
majority volume percent of the liquid composition. The polyurethane
dispersion generally constitutes at least about 0.1 volume percent of
said liquid composition.
