Road paving modified asphalt, phase separation suppression method in the production process, as well as road paving modified asphalt

摘要

[Abstract] The present invention relates to suppressing the phase separation of the modified material and asphalt. Such as A styrene-butadiene copolymer rubber or a polymer mix asphalt having at least one as a modifier of a thermoplastic elastomer such as styrene-butadiene block copolymers, such as polyoxyethylene nonyl phenyl ether, By mixing the oily surface active agent to suppress the phase separation of the modifier with the asphalt in the road paving modified asphalt.
