摘要
以SBS改性沥青A以及以其为基质沥青进行岩沥青复合改性的沥青B作为胶结料,通过试验比对应用于桥面铺装层时SMA-13与EME-10这两种混合料的路用性能。结果表明,以岩沥青复合改性SBS沥青作为胶结料的EME-10与SMA-13结构相比结构在水稳定性、高温稳定性及低温性能等路用性能方面的有着更优异的性能。
Through comparison experiment, we studied the pavement performance of SMA - 13 and EME - 10 asphalt mixture when they were applied to bridge deck pavement. In this experiment , there were two kinds asphalts used as cementing material , one was SBS modified asphalt A , the other was rock asphalt compound modification asphalt which matrix asphalt was SBS modified asphalt A , Result showed the structure of EME - lO with rock asphalt compound modification SBS asphalt as cementing material had more outstanding pavement performance than SMA -13 in the water stability, the high temperature stability and low temperature performance etc.
