Abstract

The invention relates to the field of building materials, in particular to a road paving material with solid waste as aggregate and a preparation method and application of the road paving material. The road paving material with the solid waste as the aggregate comprises a double-layer structure, a shield muck layer located on the upper layer and a substrate layer located on the lower layer and attached to the shield muck layer. The shield muck layer comprises the following raw materials in parts by weight: 30-50 parts of shield muck and 6-10 parts of a gel material; the base layer is prepared from the following raw materials: 15 to 25 parts of cement material, 10 to 20 parts of fine aggregate, 5 to 10 parts of low-quality recycled aggregate, 4 to 10 parts of bonding resin, 10 to 20 parts of modified fiber material, 1 to 1.5 parts of water reducing agent, 0.5 to 0.8 part of reinforcing agent, 3 to 8 parts of dispersing agent and 25 to 40 parts of water. The pavement material prepared by the invention not only has good mechanical properties and mechanical stability, but also can maintain excellent water resistance, aging corrosion resistance and the like in various environments, so that the performance defects of the existing pavement material are made up.
