MODIFIER FOR ASPHALT AND ASPHALT COMPOSITION FOR ROAD PAVEMENT

摘要

PROBLEM TO BE SOLVED: To provide an excellent modifier for asphalt which can lower a mixing temperature and a compacting temperature, has high softening temperature and kinematic viscosity, and can suppress formation of rust due to fluidization.;SOLUTION: A modifier for asphalt is formed of a polypropylene-based resin which contains a propylene component of 50-94 wt.% and has a weight average molecular weight of 100,000-250,000.;COPYRIGHT: (C)2014,JPO&INPIT
