Abstract: In order to study the relationship between friction coefficient and texture depth of pavement surface,and the relationship between friction coefficient of pavement surface and vehicle speed,the paper analyses the dynamic friction coefficient and texture depth of different cement concrete pavement by use of advanced tester.The result shows that friction coefficient varies with speed,and the varying rate of friction coefficient is related to texture depth.Friction coefficient decreases quicker when texture depth is deeper,and friction coefficient decreases slower when texture depth is shallower.It is showed that the friction coefficient changes with vehicle speed and texture depth,which should be paid attention in the design and management of pavement.
