Abstract

A graphene-based self-snow-melting pavement structure with shape memory function belongs to the technical field of snow-melting and ice-melting pavement, and specifically relates to a pavement structure for self-snow-melting pavement. One of the purposes of the present invention is to solve the problems of poor conductivity, crack resistance and durability of the existing conductive asphalt; the second purpose of the present invention is to solve the harsh application environment of the existing graphene heating film, short service life, It is impossible to improve the existing road surface or even if the existing road surface is improved, there will be problems of short service life and high cost. The pavement pavement structure comprises a heat insulation layer, a graphene-based conductive asphalt layer, a shape memory polymer layer, an insulating asphalt layer and a surface layer laid sequentially on the pavement from bottom to top. The graphene-based self-melting snow pavement pavement structure with shape memory function of the present invention can improve the existing pavement. The invention can obtain a graphene-based self-melting snow pavement structure with shape memory function.

Description

Technical field [0001] The present invention belongs to the technical field of road snow melting, the pavement structure particularly relates to a self-snow road surface. Background technique [0002] Winter road, bridge icy snow, frost will cause a serious decline in the ability to skid, seriously affecting road traffic safety, therefore, how timely and efficient removal of snow and ice road is important to ensure road traffic safety and capacity in winter. The current main methods of artificial snow removal snow removal, snow removal machines, snow melting agent, but these methods have snow afterwards, we can not guarantee timely removal of snow. Mechanical snow removal and artificial snow has a high cost, low efficiency and long time closed to traffic and other shortcomings, and sprinkle salt melting snow will on the one hand, can also cause long-term damage and pollution on vegetation, soil and water, therefore, is considered to be an electric snow way many roads snow removal...
