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

摘要

[Abstract] To provide a high mixing ratio is high viscosity modified asphalt asphalt modifier, be to allow phase separation suppression of a thermoplastic elastomer and asphalt by the use of oil-based surfactants. A styrene-butadiene-styrene copolymer (SBS) in modified asphalt which is formed by mixing the straight asphalt as asphalt modifier, By a combination of the compatibilizing agent and a phase separation inhibitor, and SB It is possible to obtain a phase separation suppressing effect in a high mixing region S.
