Abstract

The invention discloses an impact-resistant wear-resistant environment-friendly pavement. The pavement comprises a surface layer (1), a base layer (2), a soil cloth layer (3) and a road foundation (4), and is characterized in that the surface layer (1) is provided with a wear-resistant layer (11) and a gravel-grade steel slag layer (12); the wear-resistant layer (11) is made of ultra-high performance concrete doped with glass powder and rice hull ash; the interior of the gravel-grade steel slag layer (12) is prepared from gravel-grade waste steel slag, epoxy resin, asphalt and other materials,the base layer (2) is provided with a high-modulus epoxy asphalt steel slag layer (21) and a building reclaimed material layer (22), the building reclaimed material layer (22) is provided with a stone chip filling body (23), and the soil cloth layer (3) is located below the building reclaimed material layer (22) and above the road foundation (4) and is firm in connection. The pavement disclosed by the invention can bear received vertical, transverse and vibration impact loads, and is high in firmness, good in durability, high in comfort, high in flexibility and high in high-temperature resistance.

Description

technical field [0001] The invention relates to the technical field of airports, in particular to an impact-resistant and wear-resistant environment-friendly road surface and a construction method. Background technique [0002] The quality of the road directly affects driving comfort and safety. Roads have very strict requirements on concrete wear resistance, traffic load, durability and other indicators. [0003] Petroleum asphalt is an indispensable material in pavement materials. The performance structure directly affects the quality of asphalt pavement and driving comfort. Its use is greatly affected by temperature, and its performance is mostly improved by adding polymers. Epoxy asphalt is neither epoxy resin nor asphalt. It is a thermosetting material with multi-component interpenetrating network three-dimensional structure formed by chemical reaction through a precise component and phase design. In real life, when the temperature of the asphalt pavement is extremely...
