摘要
通过对现有评价沥青混合料低温性能的试验方法和评价指标的对比,提出低温弯曲和弯曲蠕变试验是较为经济可行的试验方法。破坏能是较好的评价沥青混合料低温性能的指标。应用低温弯曲和弯曲蠕变试验所得数据,给出了破坏能的简单计算方法。
Through comparison between test method and evaluation indexes of current evaluated asphalt mixed material, it is summarized that the low temperature bending and bending creep test is a relative economic feasi- ble test method. The rupture energy is the index to evaluate the low temperature performance of asphalt mixing material. With data obtained from low temperature bending and bending creep test, a simple calculation method is given for calculating rupture energy.
