| Abstract: | The thesis analyze the distributing of tensile stress and shearing force when the layers of semi-rigid base bituminous pavement are in completed integrate and in completed slip condition.Secondly,it analyzes the effect to the max tensile stress in the bituminous layer and the semi-rigid layer if use different slip coefficients in semi-slip and integrate condition.Thirdly,it analyze the Fatigue characteristics of bituminous pavement in completed integrate,completed slip,in semi-slip and integrate condition under the currently design criterions of bituminous pavement.Finally,it introduces the engineering experience on layers cementing by the practical project in the freeway from HuNan ChangDe to ZhangJiaJie. |
