Asphalt modifier of styrene-butadiene-styrene block copolymer and styrene-butadiene latex

摘要

This invention relates to an asphalt modifier comprising 5˜30 wt. %. of solubilized styrene-butadiene-styrene block copolymer and 70˜95 wt. % of solubilized styrene-butadiene latex, which has an excellent resistance property against plastic deformation, while preventing the occurrence of crack at a low temperature.
