A kind of pavement conductive anti-slip wear layer and preparation method thereof

Abstract

The invention discloses a pavement conductive anti-skid wear layer and a preparation method thereof. A layer of conductive carbon fiber cloth layer (6) is provided on the heat-insulating adhesive layer (7), and a layer of basalt gravel protection layer (5) is provided on the conductive carbon fiber cloth layer (6), and the basalt gravel protection layer (5) A black corundum crushed stone layer (4) is provided on the layer (5), and the overall layer thickness is 7 mm to 9 mm. The invention has high heating efficiency and is suitable for deicing and melting snow on road surfaces in winter. Since the overall layer of conductive carbon fiber cloth is relatively thin, and it is constructed at room temperature, it has the advantage of flexible construction. It is suitable for deicing and snow melting roads in winter, and improves road safety performance.

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.
