sand patch test

Through sanding test,this paper calculates the surface texture s depth of bituminous pavement and aspect ratio between ETD and texture,carries out test selecting the points with different degrees of segregation,and shows the influences of segregation on the performance of bituminous pavement through contrast of testing data,in order to solve the problem of segregation in bituminous pavement.

通过铺砂试验测算沥青路面的表面构造深度,计算ETD和构造深度比,选取不同离析程度的点进行试验,再通过试验数据对比,显示了离析对沥青路面性能的影响,以解决沥青路面的离析问题。
