A kind of composite cemented pavement pavement material and using method thereof

Abstract

The invention relates to a composite cementing pavement material and a using method thereof. The pavement material consists of a component A, a component B and a component C, wherein the mass ratio of the component A, the component B and the component C is 100 to (25-35) to (650-800); the component A is a water-borne epoxy resin emulsion which consists of water-borne epoxy resin and a flexibilizer; the component B is a water-borne epoxy curing agent; the component C consists of cement, rubber particles, stones and auxiliaries. Compared with the prior art, the pavement material has the advantages that the pavement material is free from an organic solvent, free from environmental pollution and free from fire hidden danger; the elastic modules of the pavement material can be significantly reduced, driving comfort can be improved, noise can be reduced, and a great amount of waste tires can be consumed as well, so as to promote the environment-friendly recycling utilization of the waste tires and meet national policies and guidelines on energy conservation and environmental friendliness; the pavement material is available as being uniformly stirred and does not require weighing or adding water, so that the hidden danger caused by misoperation of a constructor is eliminated; and construction tools can be directly cleaned with water, so that the pavement material is safe and convenient in operation.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to a composite cemented pavement pavement material and its application method. Background technique [0002] In recent years, with the development of the economy, the construction of high-grade highways has been very rapid. By the end of 2014, the total mileage of expressways in mainland China reached 111,950 kilometers, ranking first in the world. Compared with asphalt concrete pavement, cement concrete pavement has the advantages of strong bearing capacity, good durability, high bending and tensile strength, corrosion resistance, low engineering cost, and long service life, but its disadvantages are high rigidity, poor driving comfort, and difficult maintenance. Obviously, it hinders its further application. [0003] The rapid development of economy and transportation has caused the rapid expansion of the automobile industry. In the past two years, my country h...

Compared with asphalt concrete pavement, cement concrete pavement has the advantages of strong bearing capacity, good durability, high bending and tensile strength, corrosion resistance, low engineering cost, and long service life, but its disadvantages are high rigidity, poor driving comfort, and difficult maintenance. It is very obvious that it hinders its further application

[0003] The rapid development of economy and transportation has caused the rapid expansion of the automobile industry. In the past two years, my country has become the world's largest rubber consumer and rubber importer, with an annual output of 100 million waste tires, but the recycling rate of waste tires is only 10. %, much lower than that of developed countries

The long-term open-air stacking of waste tires not only occupies a large amount of land, but also easily breeds mosquito-borne diseases. Once a fire is triggered, the pollution is extremely serious. In view of the current severe environmental protection situation in our country, the situation of large-scale recycling of waste tires is even more urgent
