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,论述了低温弯曲和弯曲蠕变试验是较为经济可行的试验方法,破坏能是较好地评价沥青混合料低温性能的指标,并应用低温弯曲和弯曲蠕变试验所得数据,提出了破坏能的简单计算方法。
The low temperature failure and creep tests are proposed as economical and feasible test methods and damage energy is proposed as a better evaluating index based on a comparison of present test methods of evaluating asphalt mixture thermal cracking. The calculate method of damage energy is presented using the data obtained from low temperature failure and creep tests.
