摘要
利用岩石力学试验系统RMT-150B对水泥稳定碎石进行单轴、三轴和疲劳特性试验分析,得到了静态应力-应变曲线和疲劳试验曲线,结果表明:围压对提高材料的极限强度和残余强度有很大的影响,材料的动静模量存在很大的差异,并从受力状态分析了路面裂缝对路面的破坏机理。
The uniaxial compression experiment, the triaxial compression experiment and fatigue mechanism of cement - stabilized macadam were conducted by RMT system, and the static stress - strain curves and the fatigue curve were drawn. Results show that the confining pressure has great influence to the improvement of limited and remained strength, and there is great difference between dynamics and static modul. The mechanism of pavement＇ s corrosion result from crack was analyzed.
