Reflection crack resistant asphalt pavement structure and construction method thereof
The invention belongs to the technical field of road design and construction and discloses a reflection crack resistant asphalt pavement structure and a construction method thereof. The pavement structure sequentially comprises a high-performance graded broken stone base layer, a modified emulsified asphalt adhesive layer and a rock asphalt layer from bottom to top. The construction method comprises the following steps: clearing the surface of a lower supporting layer; mixing, spreading and rolling the raw material of high-performance graded broken stone; spraying the modified emulsified asphalt adhesive layer onto the surface of the high-performance graded broken stone base layer; spreading a rock asphalt modified asphalt mixture on the surface of the modified emulsified asphalt adhesive layer by using an asphalt mixture spreading machine; and then rolling by using a double-drum vibratory roller and a tyre roller. The reflection crack resistant asphalt pavement structure has the advantages that the performance advantages of all structural layers are fully exerted, the generation and development of reflective cracks of pavements are reduced and delayed, the blocking property and waterproof property between the asphalt surface layer and the base layer are increased, the asphalt pavement structure strength is increased, and the asphalt pavement performance is improved.
