Abstract:

The design procedure of a dense gap-graded friction course(DGGFC)with coarse aggregate void filling method is presented.Testing results show that a DGGFC mixture possesses a dense stone-matrix structure, good stability and almost the same texture depth as stone matrix asphalt(SMA).It also has a coarse and even surface after paving and has no separation during construction.It is durable and impermeable.It balances and improves the inherent inconsistency of asphalt mixture between the large texture depth for skid resistance and the impermeability for durability.The actual application in the Nanning-Liuzhou Expressway also shows that the performance of the DGGFC is as excellent as that of SMA, while the DGGFC mixture is cheaper than SMA.The DGGFC mixture is good for wearing course of pavement.Further research on DGGFC can be helpful for improving the surface skid resistance, prolonging the life-span period and reducing the construction costs of asphalt pavement.
