| 摘 要： | 研究了沥青混凝土路面中面层高温动态模量与车辙的关系.结果表明:提高路面中面层高温动态模量可以有效降低沥青混合料在荷载作用下的压、剪应变,加大中面层混合料向下传递荷载的扩散角,从而抵抗路面结构车辙病害;采用沥青混凝土外掺剂提高混凝土高温动态模量,性能明显优于SBS改性沥青的混合料.

| Abstract: | The relationship between the high-temperature dynamic modulus of intermediate courses of asphalt-concrete pavement and ruts in road was studied.The results showed that increasing the high-temperature dynamic modulus of intermediate courses can effectively reduce the compressive and shearing strain of asphalt-concrete mixture under traffic loading,and that increasing the divergence angle of the mixture to transfer load downwards can avoid the accidents due to road ruts.In addition,the application of modifyin... |
