摘要：
Two bituminous binders were used in this research to investigate the influence of high-temperature volatilization on the binder performance. The results indicated that at higher temperature, the weight of bituminous binder reduced and the reducing rate was decreasing with heating time. After certain volatilization period, the softening points of bituminous binder increased while the penetration reduced significantly. The volatilization condition of oxygen and vacuum did not have significant differences on the asphaltene and colloid. The bitumen binder modified with 3% of Layered double hydroxides (LDHs) would reduce the amount of VOC fumes.
