Abstract

The invention relates to an anti-aging environment-friendly modified asphalt material and a preparation method thereof. The modified asphalt material is mainly prepared from the following components in parts by mass: 60-70 parts of matrix asphalt, 15-20 parts of rubber powder particles, 5-10 parts of coarse aggregate, 5-10 parts of fine aggregate, 3-6 parts of mineral powder, 3-5 parts of polymer fiber, 1-3 parts of an antioxidant, 1-3 parts of an anti-ultraviolet agent, 0.3-0.5 part of a cross-linking agent and 0.1-0.3 part of a deodorant. According to the anti-aging environment-friendly modified asphalt material and the preparation method thereof, the formula setting is reasonable, the preparation process is simple, the prepared modified asphalt material has excellent anti-aging performance and mechanical performance, large-scale production is easy, all the components in the formula are good in compatibility, and a good synergistic effect is achieved; rubber powder particles are prepared after waste tires are treated, so that the problem of solid waste pollution caused by the waste tires is solved, waste recycling is facilitated; and the asphalt material are more environmentally friendly and economical and has a wide application prospect.

Description

Technical field[0001]The present invention belongs to the field of asphalt material, and is specifically related to modified asphalt materials for anti-aging and environmental protection and preparation methods thereof.Background technique[0002]With the continuous development of the world road construction, asphalt has become one of the most wide road pavement materials in the world.
