摘　　要：通过采用软化点差、黏度差、车辙因子差和离析率作为评价指标对现场湿法橡胶沥青(RA)、TOR改性橡胶沥青(TRA)和工厂化生产的稳定橡胶沥青(FRA)三种橡胶沥青的储存稳定性进行试验研究,结果表明:维他连接剂(TOR)对橡胶沥青的存储稳定性具有良好的改善效果,且当存储时间较长时,对TOR改性橡胶沥青的稳定性优于工厂化生产的橡胶沥青.The storage stability of wet rubber asphalt(RA),TOR modified rubber asphalt(TRA)and the stabilized rubber asphalt produced in factory(FRA)was studied by using softening point difference,viscosity difference,rut factor difference and segregation rate as evaluation indexes.The results show that trans-polyoctenamer rubber modifer(TOR)has a good effect on improving the storage stability of rubber asphalt.When the storage time is long,the stability of TOR modified rubber asphalt is better than that of the rubber asphalt which produced in factory.
