| In this paper, elastic layered system theory is employed to analyze the stress between pavement and roadbed interface under axle symmetrical loading; Discussing how stress between pavement and roadbed interface is affected by Parameter of pavement structure (including every layer s thickness. modulus of elastic Possion ratio and contact condition of interface) and study damnification of pavement structure0 Then According measured resisting slippage coefficient to analyze the condition about slippage between pavement and roadbed interface and advise technical means to prevent cutting slippage between pavement and roadbed interface... |
