摘要
采用间接拉伸疲劳试验和预裂缝试验方法,分别对正常设计70#和富油设计50#沥青混合料进行了室内试验,比较了两种沥青混合料的疲劳性能,结果表明:采用富油的设计理念后,同一级配混合料的疲劳性能得到很大的提高。
Using the indirect tensile fatigue test and pre-crack test methods,the author tests the 70# asp-halt mixture of the normal design and 50# asphalt mixture of the high-binder design,and compares with the fatigue performance of the two kinds of asphalt mixtures.The results show that the same grade asphalt mixture fatigue performance has been greatly improved after using high-binder design concept.
