| description | The utility model discloses a combined structure of an old pavement and a new pavement, which comprises a new surface layer, an old surface layer and deformed steel inserted into a groove formed between the new surface layer and the old surface layer, and the section of the deformed steel is bowl-shaped; an expansion joint is formed in the connecting part of the old base layer and the new base layer; the old cushion layer is a step-shaped old cushion layer, and an anchor piece is fixedly arranged on each step. According to the combination structure of the old road surface and the new road surface, shearing force existing between the base layers is eliminated in the mode that the base layers are separated through the structure additionally provided with the expansion joints, the vertical internal force cross sectional area between the base layers is reduced through the stepped cushion layer structures, and the anchor bar components are horizontally arranged on the vertical faces of all steps; the connection be |
