摘 要: | 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 |
| |
Abstract: | 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. |
