Abstract

The invention discloses a rubber powder epoxy resin asphalt material, as well as a preparation method and a using method thereof. Modified asphalt comprises an A component and a B component, wherein a weight ratio of the A component to the B component is 1:(2-20); the A component comprises 100 parts of epoxy resin by weight; and the B component comprises 90-120 parts of asphalt material, 10-40 parts of rubber powder material, 5-20 parts of modified monomer, 10-70 parts of fatty group binary acid and fatty acid polymer and 0.05-2 parts of accelerant. According to the rubber powder epoxy resin asphalt material, the rubber powder material is adopted, so that the unit price of the epoxy resin asphalt material can be reduced, the low-temperature flexibility of the epoxy resin asphalt material can be improved, and waste rubber can be fully used; and the rubber powder epoxy resin asphalt material, the preparation method and the using method are energy-saving and environment-friendly. The rubber powder epoxy resin asphalt material can serve as a cementing material of a bonding layer and a waterproof layer of a deck and a pavement, asphalt concrete in road engineering, top dressing and the like, and can also be used for waterproofness and anticorrosion of a structure and a building.

Description

technical field [0001] The invention relates to a modified asphalt material for road paving and its preparation method and use method, in particular to a rubber powder epoxy resin asphalt material and its preparation method and use method. Background technique [0002] Due to the continuous development of my country's transportation industry, the scale of road construction has gradually expanded, especially the mileage of high-grade road construction has continued to increase, and the demand for high-quality road asphalt is on the rise. At the same time, due to the rapid increase of the traffic volume due to the development of the national economy, the large-scale vehicles and the heavy load of the vehicles have put forward higher requirements for the quality of the asphalt pavement. In this case, ordinary asphalt cannot meet the requirements, and more and more pavements or steel bridge deck pavements use polymer-modified asphalt. Commonly used polymer-modified asphalt is t...
