AI Technical Summary

Problems solved by technology

The main causes of road surface damage include the direct impact of repeated rolling of rubber wheels and the external environment. In the lightest cases, cracks and ruts appear, which affect driving comfort; in severe cases, potholes appear, endangering the overall stability and safety of the road surface; There will be a long interruption of traffic

Abstract

Currently, a road surface structure in a tunnel is composed of conventional asphalt concrete and fracture-resistant concrete or steel fiber concrete. Primary causes of road surface damage comprise direct impact of repeated crushing of rubber wheels and external environmental effects, at best, cracks and tracks are generated, the riding comfort is affected, at worst, pits and grooves are generated, and the overall stability and safety of the road surface are threatened; and even traffic is delayed for a long time during later maintenance. To improve the fracture resistance and pressure resistance of the road surface, prolong the service life of the road surface and recover the road surface rapidly during later maintenance, the invention provides a tramcar basalt fiber composite road surface structure, and the tramcar basalt fiber composite road surface structure sequentially comprises a basalt fiber concrete base layer, a basalt fiber medium grain type asphalt concrete layer and a basalt fiber asphalt mastic gravel mixed aggregate layer from bottom to top.

Description

technical field [0001] The invention relates to a pavement structure, in particular to a tram basalt fiber composite pavement structure. Background technique [0002] The rapid development of cars has made urban traffic congestion, parking difficulties, public transportation speed reduction, travel difficulties and other problems increasingly serious, and the energy consumption, air pollution, environmental degradation and other problems caused by it have attracted people's attention. The deteriorating urban traffic problems, We have to pay attention to the sustainable development of urban public transportation, and it has gradually become a consensus to accelerate the construction of a resource-saving and environment-friendly public transportation industry. The developed and upgraded tram has the characteristics of high transport capacity, high speed, low pollution, etc., conforms to the contemporary concept of low-carbon, green, and environmental protection, and is in line...
