Abstract

The invention relates to an environment-friendly warm-mix asphalt rejuvenator and a preparation method thereof. The invention belongs to the field of road engineering and aims to solve the problems of poor diffusion effect of existing asphalt rejuvenator materials and high mixing temperature. Preparation method: 1. Weigh bio-asphalt, epoxidized soybean oil, curing agent, straw fiber and epoxy resin as raw materials; 2. Put bio-asphalt in the raw material in a reactor, add curing agent, Stir evenly at high temperature to obtain a mixture, add epoxidized soybean oil in the raw material, stir at a temperature of 50-60°C, add straw fiber, and continue stirring at a temperature of 50-60°C to obtain an effective component of the regenerant; The effective components of the agent are mixed with the epoxy resin in the raw material. The invention adopts bio-asphalt and other effective components to restore the performance of aged asphalt, enhances the diffusion effect through epoxy soybean oil, and realizes the warm-mix production of recycled asphalt mixture, and the production process is simple and energy-saving.

Description

Technical field [0001] The present invention belongs to the field of road engineering, specifically relates to an environmentally friendly warm-mix asphalt regeneration agent and a preparation method thereof. Background [0002] By the end of 2018, the total length of China's highways reached 4.8465 million kilometers, of which the highway maintenance mileage accounted for 98.2% of the total highway mileage, while the secondary and above highway mileage reached 647,800 kilometers, of which a considerable part of the use of asphalt concrete pavement, so that tens of millions of tons of waste asphalt mixture (RAP) will be generated every year due to road maintenance and repair projects. At present, the comprehensive disposal of RAP is gradually becoming an important research content for the sustainable development of the transportation field, and the "Outline for the Construction of a Transportation Powerhouse" also points out that "to promote the conservation and intensive utiliza...
