Application of Graded Crushed Stone Base in Urban Road Asphalt Pavement

Zhang, Peiliang / Liu, Jinyan / Wu, Yingbiao / Shi, Jinjin

Combining the characteristics of graded broken stone (GBS) and SRB, a pavement base structure with cement stabilized recycled masonry aggregate (CRMA) and upper base of GBS was adopted in a road project in Cangzhou City (CZC). The indoor test determined that the optimal water content (OWC) of the GBS mixture was 3.2% and the maximum dry density (MDD) was 2.197 g/cm³; OWC of CRMA is 14.3%, and MDD is 1.81 g/cm³. The investigation results of pavement deflection and cracks in the six years of opening to traffic show that the asphalt pavement structure with the lower base (LB) of SRB and the upper base (UB) of GBS has good crack resistance.
