Abstract

The invention relates to the technical field of asphalt materials, and provides an environment-friendly asphalt mixture aiming at the problem that the asphalt mixture is easy to deform due to pressure, the environment-friendly asphalt mixture comprises the following components: 100 parts of asphalt; 100 to 120 parts of waste rubber particles; 150 to 180 parts of gravels; 120 to 150 parts of a fineaggregate; 5-8 parts of copper pyrithione; and 1-3 parts of oxine copper. The invention also provides a preparation method of the environment-friendly asphalt mixture, and the method comprises the following steps: S1, heating the asphalt to 160-170 DEG C, adding the copper pyrithione and the oxine copper, and uniformly stirring to form a premix; s2, adding the waste rubber particles and the fineaggregate into the premix, and uniformly stirring to form a mixture; s3, adding the gravels into the mixture, and uniformly stirring to form the environment-friendly asphalt mixture. The copper pyrithione and the oxine copper are added into the asphalt and are matched with the asphalt according to a specific ratio, so that the compressive strength of the asphalt is effectively improved, the structural stability of a road paved by the asphalt mixture is relatively good, and the situations of deformation, cracking and the like caused by compression are not easy to occur.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, in particular to an environment-friendly asphalt mixture and a preparation method thereof. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] ...
