| Abstract: | The different construction methods result in different state of interlayer between completely continuous and continuous smooth during the construction of the large thickness cement stone layer.Based on the measured data calculated FWD interlayer bonding coefficient,the road surface deflection was calculated under different binding state by introducing the coefficient of deflection in this article;finally the reliability of calculation methods was verified by the test road paving. |
