Noise reduction type semi-flexible anti-rutting asphalt pavement structure

The utility model discloses a noise reduction type semi-flexible anti-rut asphalt pavement structure, which relates to the technical field of pavement structures and comprises a concrete base layer, a gravel layer is arranged at the top end of the concrete base layer, a modified asphalt layer is arranged at the top end of the gravel layer, and an anti-rut layer is arranged at the top end of the modified asphalt layer. A plurality of metal shells vertically penetrate through the interiors of the anti-rutting layer, the gravel layer and the modified asphalt layer, and rib plates are welded to the outer walls of the metal shells. Due to the fact that the metal shell and the rib plates are arranged, the stability between the layers of the structure is improved, cracking and separation between the layers are avoided, meanwhile, the bearing capacity of the structure is improved, deformation of the structure under long-term high pressure can be avoided, the service life of the structure is guaranteed, the anti-rut l
