| 摘 要： | 利用MTS810型液压伺服试验系统和旋转压实仪GC(Gyratory Compactor)进行沥青混合料的五级单轴压缩蠕变试验,研究了重荷载下沥青混合料的高温稳定性。从能量的角度分析了沥青混合料的永久变形机理,并找出了耗散能与永久变形的关系,通过多元回归得到了重载交通下沥青路面的车辙预估模型。

| Abstract: | With the use of MTS 810 electo-servo controlled testing system and GC (gyratory compactor ), a five stage uniaxial compression creep test is applied to study the high air temperature stability of asphalt mixture under heavy loading. The energy method is applied to analyse the mechanism of permanent deformation. And the relationship of dissipation energy and permanent deformation is obtained. The prediction model of rutting under heavy loading is formed from multiple factor regression analysis. |
