Abstract

The invention discloses an asphalt regeneration agent which is prepared from the following raw materials in percentage by mass: 65-80% of plant asphalt, 3-5% of an interface reinforcing modifier, 15-30% of a plasticizer, 0.3-1% of a penetrating agent and 0.5-1% of an anti-aging agent, wherein the interface reinforcing modifier is one or a mixture of more than two of epoxy aliphatic polyethylene polyamine, epoxy silicon resin and epoxy resin in any ratio; the content of the epoxy group in the interface reinforcing modifier is 10-40%. In addition, the invention further provides a preparation method of the asphalt regeneration agent, an asphalt mixed material prepared from the asphalt regeneration agent, and a preparation method of the asphalt mixed material. When the asphalt mixed material is prepared from the asphalt regeneration agent, the anti-rutting performance, the anti-water damage property and the low-temperature anti-cracking property can be greatly improved, and waste resources can be recycled.

Description

technical field [0001] The invention belongs to the field of road building materials, and in particular relates to an asphalt regenerant and its preparation method and application. Background technique [0002] With the accelerated pace of highway construction in our country, road maintenance and repair tasks have intensified. Every year, tens of millions of tons of old pavement materials (RAP) are generated during road reconstruction, renovation or maintenance. How to deal with old pavement materials reasonably and effectively, and how to effectively protect the ecological environment while developing roads, will become must face the problem. According to the existing research experience, using asphalt regeneration technology to recycle old pavement materials will be an effective method to solve the problem of pavement old materials. The research idea of ​​traditional asphalt mixture regeneration is to soften the aging and hardened asphalt by adding rejuvenating agent, so...
