广西宜河高速橡胶沥青路面和SBS改性沥青路面性能对比研究

依托广西宜河高速公路开展橡胶沥青路面结构形式的试验路铺筑（7 cmARAC-20C下面层+5 cmARAC-13C上面层），与正常路段的SBS改性沥青路面结构形式（8 cm 70号道路石油沥青AC-25C下面层+6 cm SBS改性沥青AC-20C中面层+4 cm SBS改性沥青AC-13 C上面层）进行对比，并开展沥青胶结料、成品混合料室内性能、现场抗滑指标试验以及长期路用性能观测评价对比研究。结果表明:两种路面结构的使用性能相当。

Comparative Study on Performance of Rubber Asphalt Pavement and SBS Modified Asphalt Pavement of Yihe Expressway in Guangxi

Relying on in the test section of Yizhou—Hechi Expressway, Guangxi, the pavement structure laying rubber asphalt (7 cm ARAC-20C lower layer+5 cm ARAC-13C upper layer), the comparison with in the normal sections the SBS modified asphalt pavement structure (8 cm No.70 pavement petroleum asphalt AC-25C lower layer+6 cm SBS modified asphalt AC-20C middle layer+4 cm SBS modified asphalt AC-13C upper layer) was carried out to study the laboratory performance and field anti-sliding index by tests, and then to make observation and evaluation of long-term pavement performance. The result shows that the two kinds of pavement structure have the equivalent performance.
