ABSTRACT:
The present invention provides an aqueous emulsion joint and crack filler capable of passing the ASTM Specification 1190 for joint and crack fillers. The emulsion solids are the reaction product of asphalt, an extender oil, a mixture of elastomers, an acrylamide and a vinyl monomer. The preferred elastomer mixture includes a liquid rubber and at least one block copolymer of styrene and a conjugated diene, such as triblock and diblock copolymers of styrene and butadiene. The preferred emulsion medium is water containing a surfactant and an acrylamide polymer. The emulsion is poured at ambient temperature into a joint or crack, and cures rapidly to ensure minimal traffic interruption.
