摘要
结合对部分高速公路车辙调查结果,发现中面层处于剪应力峰值区域,中面层的车辙变形对沥青路面车辙变形的影响最大,有必要采用基于抗车辙性能的试验方法进行中面层混合料的设计。比较目前常用的3种混合料设计方法,推荐SGC混合料设计方法。
Based on the results of investigation on some ruts of expressway, this paper draws a conclusion that the intermediate surface is in the area of peak shear stress and the deformation of ruts in intermediate surface has the biggest influence on the deformation of ruts in asphalt pavement, therefore, it is necessary to design the mixtures for intermediate surface by adopting the test method based on anti-rut performance. Next the paper compares the design methods for three common mixtures at present and recommends the design method for SGC mixture.
