| 摘 要： | 结合云南永武高速公路建设的实际情况,通过对混合料级配和沥青用量的优化设计,改善了初次级配设计中因细料过多而影响高温稳定性的现象。经车辙试验、马歇尔试验及48 h稳定度试验证明,该级配设计提高了路面路用性能,显著地增强了路面的高温稳定性。

| Abstract: | According to the construction realities of Yunnan Yongwu highway,through optimizing design of the mixture gradation and asphalt content,the influence of excessive fines on mixture temperature stability is improved. The results of rutting test,Marshall test and 48 h stability test show that the designed mixture gradation improves road performance and the high temperature stability of pavement significantly. |
