Modular self-snow-melting pavement based on graphene

Abstract

The invention discloses a modular self-snow-melting pavement based on graphene and relates to a conductive asphalt pavement. The invention aims to solve the problem that the modular conductive asphaltpavement joint sealing material cannot meet the requirement that the expansion joint is damaged due to the influence of pavement environment change. The problems of discontinuous conduction, energy waste and influence on the ice and snow melting effect due to incapability of adapting to pavement joint and crack width change and incapability of forming a conductive network of the assembled conductive asphalt pavement are solved; the problems that a conductive asphalt pavement is poor in high-temperature stability, low-temperature crack resistance, water stability and fatigue resistance and lowin conductivity are solved. In the modular self-snow-melting pavement, the graphene conductive asphalt layer plays a role in electric conduction and heating, and the conductive shape memory compositematerial is filled in the joint, can actively cater to the width change of the joint and the crack of the pavement, and can be better attached between unit asphalt pavements of the modular self-snow-melting pavement according to the environment change of the pavement so as to realize the joint connection and electric conduction continuity effect. The invention is applied to the field of self-snow-melting pavements.

Description

technical field

[0001] The invention relates to a conductive asphalt pavement; in particular, it relates to a graphene-based modularized self-melting snow pavement. Background technique

[0002] my country's four seasons climate changes are obvious, especially in late autumn, winter and early spring, affected by cold air, the temperature changes significantly, bringing a lot of rainfall and snowfall, making the road surface prone to snow and ice accumulation, which in turn has a great impact on road traffic. Ice and snow are extremely detrimental to the drivability and safety of driving vehicles. According to statistics, about 15% to 30% of traffic accidents in winter are related to road snow, especially on expressways, which are very prone to serious traffic accidents such as continuous rear-end collisions. Severe snow on the road will cause the road to be closed, which will seriously affect the smooth flow of the road and cause huge economic losses.
