摘要
首先通过室内模拟降温找出沥青稳定碎石(ATB30)的温降规律,得出温降速度,然后分析马歇尔试验结果,确定混合料的碾压控制温度,结合温降速度与碾压控制温度对混合料的有效压实时间进行预估。
At first, the authors obtain the rule of temperature descent for asphalt stabilized macadam （ATB30） through simulating the course of temperature descent inside, in order to know the speed of temperature descent. Through analyzing the outcome of Marshall experiment, it is possible to confirm the roll-controlling temperature of asphalt mixture, and then to estimate the effective compaction time from the temperature descent speed and roll-controlling temperature together.
