Embodiment

[0021] The preparation process of waste plastic modified asphalt concrete is:

[0022] 1) The selection of raw materials, that is, the selection of rubber granules, asphalt and single-grain crushed stones processed from waste plastics;

[0023] a. Rubber granules processed from waste plastics: 92% waste rubber floor granules (or waste tire granules), 4% carbon black, 2% calcium carbonate and 2% accelerator DM (chemical name: 2, 2'-dithiodibenzothiazole) mixed composition, through 25 mesh sieve. The waste rubber floor particles are ethylene-propylene rubber.

Abstract

The invention relates to asphalt concrete, and particularly relates to waste plastic modified asphalt concrete. The waste plastic modified asphalt concrete is characterized by comprising rubber particles formed by processing waste plastic, asphalt and single-gradation broken stones which are bended according to a ratio through rubber asphalt processing equipment. The waste plastic modified asphalt concrete has the advantages of making full use of the waste rubber, avoiding wasting of resources, saving cost and simultaneously solving the problems that roads paved by conventional asphalt concrete are easy to age, the conventional asphalt concrete easily results in reflection cracks of road surfaces, and the using function of the road surface is seriously affected by cracking and slurry spurting of the conventional asphalt concrete in a using process.

Description

technical field [0001] The invention relates to an asphalt concrete, in particular to a waste plastic modified asphalt concrete, which belongs to the field of road construction. Background technique [0002] Asphalt concrete (English: bituminous concrete) is commonly known as asphalt concrete, which is artificially selected with a certain gradation of mineral materials (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, A mixture made under strictly controlled conditions. The road paved with asphalt concrete has high cost, is easy to age, and is easy to cause reflective cracks on the road surface. During the use process, damage phenomena such as cracking, pumping, and loosening occur, which seriously affect the use function of the road surface. Especially in the high temperature season in summer, the structural layer that is prone to rutting on the asphalt pavement is the middle surface layer. When...
