Problems solved by technology

[0004] However, due to the softness of the asphalt mixture, when the weight of the vehicle is too large, the asphalt mixture is easily deformed under pressure, causing the road surface to sag, crack, etc., resulting in frequent asphalt pavement repairs, so there is still room for improvement

Abstract

The invention relates to the technical field of asphalt materials. Aiming at the problem that the asphalt mixture is easily deformed under pressure, an environmentally friendly asphalt mixture is provided. The technical solution is as follows: including: 100 parts of asphalt; 100-120 parts of waste rubber particles; 150 parts of gravel ‑180 parts; 120‑150 parts of fine aggregate; 5‑8 parts of copper pyrithione; 1‑3 parts of copper quinoline. Also provided is a method for preparing an environmentally friendly asphalt mixture, comprising the following steps: S1. heating the asphalt to 160-170° C., adding copper pyrithione and copper quinoline, and stirring evenly to form a premix; S2. premix Add waste rubber particles and fine aggregates to the mixture, and stir to form a mixture; S3. Add gravel to the mixture, and stir to form an environmentally friendly asphalt mixture. By adding copper pyrithione and copper quinoline to asphalt, and blending with asphalt in a specific ratio, the compressive strength of asphalt can be effectively improved, so that the road structure paved with asphalt mixture has better stability and is less likely to be caused by compression. And deformation, cracking and so on.

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] ...
