Asphalt pavement structure based on coordination of deformation of subgrade and pavement
The invention provides an asphalt pavement structure based on the coordination of the deformation of a subgrade and a pavement. The pavement structure comprises an asphalt pavement layer, an anti-fatigue semi-rigid base layer and a sub-base layer in sequence from top to bottom, wherein the asphalt surface layer comprises a surface layer, a middle surface layer and a lower surface layer; the surface layer is located on the upper surface of the asphalt pavement layer; the middle surface layer is paved under the surface layer; the lower surface layer is paved under the middle surface layer; sticking layer oil is sprayed among the surface layer, the middle surface layer and the lower surface layer respectively; the anti-fatigue semi-rigid base layer is paved under the lower surface layer; prime coat oil is sprayed between the anti-fatigue semi-rigid base layer and the lower surface layer; and the sub-base layer is paved on the subgrade. The influences on the pavement structure, caused by the non-uniform deformation of the subgrade, can be effectively alleviated.
