施工温度对排水沥青路面的稳定性和耐久性影响很大。为模拟施工压实温度变异性对排水沥青混合料性能的影响,室内分析了不同压实温度下排水沥青混合料的空隙率、马歇尔稳定度、肯塔堡磨耗损失率和劈裂强度的变化。结果表明:压实温度尽管对排水沥青混合料的体积特性影响不甚明显,但对混合料的稳定性和耐久性影响很大,应严格控制排水沥青路面的施工温度。
Construction temperature has a great influence on the stability and durability of drainage asphalt pavement. In order to simulate the influence of compaction temperature variability on the performance of drainage asphalt mixture, the variation of voidage, Marshall stability, abrasion loss and splitting strength of drainage asphalt mixture at different compaction temperatures were analyzed indoors. The results show that although the compaction temperature has little effect on the volumetric characteristics of drainage asphalt mixture, it has a great influence on the stability and durability of the mixture. The construction temperature of drainage asphalt pavement should be strictly controlled.
