摘要
我国评价沥青混合料的高温抗车辙能力一般采用车辙板试验,试验指标采用动稳定度。本文主要就动稳定度试验时所采用的试验温度、车辙板厚度、荷载压力、车辙板压实度等进行试验与评价。试验结果表明,车辙板的试验条件对沥青混合料的高温抗车辙性能有很大的影响。
Dynamic stability test is the main method to evaluate HMA high temperature performance with test index to indicate dynamic stability. Main factors such as temperature, plate depth, load pressure and compact index are studied in this paper. The results show that the test conditions have significant effect on HMA high temperature performance.
