Problems solved by technology

[0003] However, when construction waste is used as recycled aggregate in the road, it will increase the porosity in the road layer structure, making it easy for water to stay in the road layer structure. Under the action of high-speed driving load, the water will cycle repeatedly in the road layer structure. The dynamic water pressure will continue to damage the bond between the asphalt and the aggregate, and the asphalt will be easily peeled off from the surface of the aggregate, which will have a negative impact on the load strength and service life of the road. Further improvement is needed

Abstract

The invention relates to the field of road engineering, in particular to a pavement structure of a recycled aggregate asphalt concrete pavement, and solves the problems that water is easy to retain in a road layer structure, the water continuously destroys the bonding force between asphalt and aggregate in the road layer structure under the action of high-speed traffic load, the asphalt is easy to peel off from the surface of the aggregate, and the service life of the pavement structure is prolonged. The pavement structure comprises an upper surface layer, a middle surface layer, a lower surface layer and a pavement base layer which are sequentially laid from top to bottom, a water retaining layer is embedded in the pavement base layer, and the middle of the water retaining layer is higher than the two sides of the water retaining layer. The road layer structure has the advantages that drainage of the road layer structure is facilitated, and adverse effects of water on the road layer structure are reduced.

Description

technical field [0001] The application relates to the field of road engineering, in particular to a pavement structure of recycled aggregate asphalt concrete surface. Background technique [0002] With the promotion of hardened pavement and the rapid development of urbanization in our country, when the pavement reaches the service life or is damaged due to other reasons, it will generate a large amount of construction waste, such as steel and concrete. Blocks and asphalt concrete, these construction wastes are inorganic materials with good durability and will not decompose naturally, so they are often reused as recycled building materials or recycled aggregates for road surfaces, which can not only solve the environmental pollution of construction waste, but also reduce sand mining. [0003] However, when construction waste is used as recycled aggregate in the road, it will increase the porosity in the road layer structure, making it easy for water to stay in the road layer...
