摘要
粉胶比对沥青路面使用性能影响显著,合适的粉胶比是沥青混合料设计和施工过程中控制的重点。通过室内试验分析不同粉胶比下沥青胶泥和沥青混合料的高温、低温、抗水损害、抗疲劳性能,提出重庆高速公路沥青混合料合适的粉胶比范围。
Filler-bitumen ratio has obvious influence to performance of asphalt pavement,a proper filler-bitumen ratio will be the key for asphalt mixture design and construction control.By analyzing high temperature, low temperature,anti-water damage and anti-fatigue performance of asphalt grout and asphalt mixture under different filler-bitumen ratio,this paper suggests the suitable range of filler-bitumen ratio for Chongqing expressways.
