Abstract

The invention discloses high-dosage rubber-plastic composite rubber powder modified asphalt. The high-dosage rubber-plastic composite rubber powder modified asphalt is mainly prepared from the following raw materials in parts by weight: 15-40 parts of rubber-plastic composite rubber powder and 100-200 parts of matrix asphalt, the rubber-plastic composite rubber powder is prepared from 70-90 partsof waste tire rubber powder and 10-30 parts of waste plastic through a double-screw extruder. Accordingly, a corresponding preparation method is established. Researches show that the high-dosage rubber-plastic composite rubber powder modified asphalt which takes high-mixing-amount rubber-plastic composite rubber powder as a main material and takes a small amount of materials as an auxiliary material has good high and low temperature performance, construction stability, elastic recovery performance and storage stability; the process is simple and easy to operate, and continuous large-scale production and preparation can be realized. In addition, the waste tire rubber powder and the waste plastics can be absorbed in large quantities by widely popularizing the method, and huge ecological andeconomic benefits are brought to the social environment.

Description

technical field

[0001] The invention belongs to the technical field of modified asphalt, and in particular relates to a high-volume rubber-plastic composite rubber powder modified asphalt and a preparation method thereof. Background technique

[0002] With the continuous progress of industrialized life in society, on the one hand, a considerable number of industrialized products bring great convenience to the public, and on the other hand, a huge amount of solid waste is derived, which brings great pressure to the ecological environment. Waste tires Quantity and Waste plastics are typical solid wastes with large annual output, difficult to degrade in nature, and great environmental hazards. With the continuous progress of society, people are generally aware of the hazards of these solid wastes, and gradually begin to find ways to recycle them. Road modified asphalt provides a good platform for utilization. Relevant studies have shown that rubber powder made from waste tires...
