摘要:
采用间接拉伸试验,对不同温度、不同加载速率、不同沥青含量及不同级配下的沥青混合料间接拉伸试验(IDT)强度进行了研究,结果显示:温度和加载速率是影响试验结果的两个重要条件.通过将间接拉伸试验结果与车辙试验结果进行对比分析后发现,当试验温度为40℃和加载速率为50mm/min时,混合料的IDT强度与车辙结果之间的相关性最好,可以作为评价沥青混合料高温性能的力学指标,建议在沥青混合料设计过程中采用.
Abstract:
The indirect tensile test (IDT) strength of asphalt mixture under different temperatures, different loading rates, different asphalt content and different grades was studied by indirect tensile test, and the results showed that temperature and loading rate were two important conditions affecting the test results. By comparing and analyzing the indirect tensile test results with the rutting test results, it is found that when the test temperature is 40°C and the loading rate is 50mm/min, the correlation between the IDT strength of the mixture and the rutting results is the best, which can be used as a mechanical index to evaluate the high temperature performance of asphalt mixture, and it is recommended to use it in the design process of asphalt mixture.
