Asphalt pavement structure applicable to expansion deformation of black cotton soil subgrade
The invention provides an asphalt pavement structure applicable to the expansion deformation of a black cotton soil subgrade. The pavement structure comprises an asphalt pavement layer, a dense-graded asphalt gravel base layer, an interlayer and a sub-base layer in sequence from top to bottom, wherein the asphalt pavement layer comprises a surface layer and a lower surface layer; the surface layer is located on the upper surface of the asphalt pavement layer; the lower surface layer is paved under the surface layer; sticking layer oil is sprayed between the surface layer and the lower surface layer; the dense-graded asphalt gravel base layer is paved under the lower surface layer; sticking layer oil is sprayed between the dense-graded asphalt gravel base layer and the lower surface layer; the interlayer is paved under the dense-graded asphalt gravel base layer; and the sub-base layer is paved on the subgrade. According to the asphalt pavement structure, the influences of additional stress on a pavement, caused by the non-uniform deformation of the black cotton soil region subgrade, can be effectively alleviated and the pavement cracks are reduced.
