摘要
应用正交试验设计方法指导优化室内疲劳试验,通过直观分析和方差分析研究了不同的级配、沥青品种、油石比、应变水平、间歇时间和试验温度对混合料疲劳性能的影响程度;并结合实际对各个因素的影响规律进行了分析,可为沥青混合料的抗疲劳设计提供一定的参考。
The influence level of gradation, asphalt range, bitumen-aggregate ratio, strain level interval time and test temperature on fatigue performance of mixture is studied through intuitive analysis and variance analysis by carrying out optimized indoor fatigue test with guidance of orthogonal test, The influence rule of all factors is analyzed, which provides reference for fatigue-resistance design of asphalt mixture.
