不同中面层沥青混合料抗车辙性能研究

通过研究发现沥青路面的车辙破坏往往发生在沥青路面的中面层。基于此通过对比分析中面层材料设计时常用的三种沥青混合料的高温抗车辙试验,并通过动稳定度、相对变形、综合稳定系数三个评价指标,综合评价了三种中面层沥青混合料的高温抗车辙性能,为以后高等级沥青路面中面层材料设计提供理论指导参考。

Research on Rutting-resistance Performance of Bituminous Mixture with Different Mid-surface Layer

Through research we have found that wheel rut damages of bituminous pavement often occur in the mid-surface layer of the bituminous pavement. Based on this, through comparison and analysis of high temperature rutting test for the three kinds of bituminous mixture normally adopted for mid-surface layer design, and through the three evaluating factors as dynamic stability, relative deformation and synthesis stability coefficient, the high temperature rutting-resistance performance of the three kinds of bituminous mixture have been evalued, which will provide theoretics instruction for the later high-grade bituminous pavement.
