Problems solved by technology

Asphalt pavement is a flexible pavement, which is flat and comfortable to drive, but has a short lifespan and is prone to ruts, cracks, pits, looseness and other diseases; cement concrete pavement is a rigid pavement with high strength, strong bearing capacity and good durability, but The driving noise is loud, the comfort is poor, and it is also prone to cracks, broken boards, misplaced platforms, broken, voids or cavities, etc., and its maintenance time is long and it is difficult to repair
The disadvantages of traditional asphalt concrete pavement and cement concrete pavement are becoming more and more obvious, and it is becoming more and more difficult to meet the requirements of road construction development

Abstract

The invention relates to a concrete pavement material for heavy traffic roads and a preparation method thereof. The material is composed of a component A, a component B and a component C in a mass ratio of 1:(0.2-0.6):(4-8). The component A comprises the following components in parts by mass: 40-80 parts of epoxy resin, 0-20 parts of epoxy reactive diluent, 10-50 parts of elastic modifier, 0.2 part of defoaming agent and 0.2 part of dispersing agent. The component B comprises the following components in parts by mass: 100 parts of curing agent, 0-10 parts of curing accelerator and 1 part of coupling agent. The component C comprises the following components in parts by volume: 100 parts of fine stone, 30-300 parts of fine sand, 130-800 parts of waste rubber particle, 50-100 parts of waste rubber powder and 10-20 parts of crystal whisker. Compared with the prior art, the concrete pavement material for heavy traffic roads has the advantages of high strength, favorable durability, favorable roadability, energy saving, environment friendliness and the like, and is convenient for construction.

Description

technical field [0001] The invention belongs to the technical field of chemical road materials, and in particular relates to a concrete pavement material suitable for heavy traffic roads and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's national economy and highway transportation, the characteristics of heavy traffic on highways have become more and more prominent. The proportion of heavy-duty trucks in transportation vehicles is increasing, and the total load quality and axle load quality of vehicles are constantly improving, and they are becoming larger and larger. Heavy-duty vehicles with single axle exceeding 10t, double axle exceeding 18t and three axle exceeding 22t have become an important part of transportation. At the same time, with the improvement of people's living standards and the enhancement of environmental protection awareness, higher requirements have been put forward for the safety,...
