Electric-conduction anti-skid wearing layer for pavement and preparation method thereof

Abstract

The invention discloses an electric-conduction anti-skid wearing layer for a pavement and a preparation method thereof. An electric-conduction carbon fiber cloth layer (6) is arranged on a heat-insulation bonding layer (7) and is provided with a broken basalt protection layer (5); and the broken basalt protection layer (5) is provided with a black corundum metalling layer (4), and is integrally 7mm-9mm in thickness. The electric-conduction anti-skid wearing layer has high heating efficiency, and is suitable for deicing and snow melting on the pavements in winter. The electric-conduction carbon fiber cloth layer is thin integrally, and is constructed at normal temperature, thus having the advantages of flexible construction; and the electric-conduction anti-skid wearing layer is suitable for deicing and snow melting on the pavements in winter, so that the driving safety on the pavements is improved.

Description

technical field [0001] The invention relates to a road surface, in particular to a conductive anti-skid wear layer for the road surface. The invention also relates to a preparation method of the conductive anti-skid wear layer for the road surface, which is mainly used for melting ice and snow on the road surface in winter. Background technique [0002] With the continuous development of my country's modernization, the continuous improvement of the national economic level, the construction of a large number of expressways and urban viaducts, and the continuous increase in the number and speed of cars, how to improve the operation of roads and ensure driving safety is a topic that all countries attach great importance to. Among them, snow and ice on roads in winter is a major hidden danger to safe driving. [0003] Snow and ice on the road in winter will cause traffic jams, increase the braking distance of vehicles, and cause accidents such as skids, rollovers or rear-end col...

AI Technical Summary

Problems solved by technology

[0007] However, there are still key problems to be solved in thermal ice and snow melting technology: for the built-in cable thermal ice melting technology, the built-in cables and steel pipes will lead to stress concentration on the road surface, and the asphalt material will soften when heated, causing road surface diseases; for conductive concrete, there are High heat load, difficult construction, low heating efficiency, etc.

[0008] At present, most electric heating methods use 220V AC voltage power supply. Under the long-term vehicle load on the road surface, it may cause cracks on the road surface and damage to the heating cable and protective tube.
