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 a preparation method and application thereof. Background technique [0002] With the acceleration of highway construction in my country, the maintenance and repair tasks of roads are intensified. Every year, tens of millions of tons of old pavement materials (RAP) are generated in the process of road reconstruction, renovation or maintenance. How to deal with the old pavement materials reasonably and effectively, and how to effectively protect the ecological environment while the road is developing, will become an important issue. problems that must be faced. According to the existing research experience, the use of asphalt recycling technology to recycle old pavement materials will be an effective method to solve the problem of old pavement materials. The research idea of ​​the traditional asphalt mixture regeneration is to soften th...
