| 摘 要： | 根据厚沥青面层的自身受力特点,采用应力控制模式对旋转压实剪切实验机(GTM)旋转压实与马歇尔击实两种设计方法下的不同混合料的疲劳性能进行了对比评价.研究表明在材料试验设备MTS810上采用应力控制模式比较与评价不同设计方法下混合料的疲劳性能是可行的,在应力控制模式下旋转压实设计出的混合料疲劳性能优于马歇尔击实设计出的沥青混合料疲劳性能,并研究了公称最大粒径对混合料疲劳性能的影响.

| Abstract: | Fatigue cracking is considered to be a major distress affecting the performance of asphalt pavements.Study on asphalt mixes fatigue performance is mainly carried out through the controlled-stress mode and is used on structure design.Stress-controlled mode can reflect responses in thicker pavements.So it is used to evaluate fatigue performance of different asphalt content mixtures which are designed by Gyratory Testing Machine(GTM) and Marshall hammer respectively.Stress-controlled mode based on MTS810 proves effective in evaluating asphalt mixture fatigue performance.GTM mixture fatigue performance proves superior to Marshall mixture fatigue performance.Besides,the effect of nominal maximum aggregate size on asphalt mixture fatigue performance is studied. |
