摘要:
采用劈裂试验方法,分别对新拌、短期老化和长期老化状态下沥青混合料的低温性能进行了对比研究.试验表明,未老化的沥青混合料的低温性能不能反映和预测老化后的性能,并且在评价沥青混合料低温性能时,短期老化试验比长期老化试验更为敏感,由此说明在沥青混合料低温性能试验评价过程中充分考虑老化因素的影响是必要的.
Abstract:

The low-temperature performance of asphalt mixture under fresh, short-term aging and long-term aging was compared by splitting test method. The test shows that the low-temperature performance of the unaged asphalt mixture cannot reflect and predict the performance after aging, and the short-term aging test is more sensitive than the long-term aging test when evaluating the low-temperature performance of asphalt mixture, which indicates that it is necessary to fully consider the influence of aging factors in the low-temperature performance test evaluation process of asphalt mixture.
