Abstract

The invention belongs to the technical field of road engineering materials and particularly relates to a method for preparing an asphalt regenerating agent based on discarded tires. The discarded tires are used as raw materials firstly and are processed to obtain discarded tire granules, then the discarded tire granules and a home-made biological fluid are put in a fermentation tank for fermentation, a fermentation mixture is obtained, then platinum tetrachloride is used as a catalyst, splitting decomposition is conducted on the fermentation mixture through high temperature and high pressure, a discharged substance is filtered, filtrate and amino cyclopropane carboxylic acid are mixed, distillation is performed to obtain a fraction, finally the fraction is mixed with sodium sulfamate and other substances, and the asphalt regenerating agent can be obtained. The discarded tires are used as raw materials, the cost is reduced, waste recycling is achieved, microbes in rubber barks are screen and cultured and then are filtered, a target culture solution is obtained and is used for conducting biological decomposition and modification on the discarded tire granules, the activity is increased, and further the rapidity of the asphalt regenerating agent permeating into an asphalt inside layer is improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a method for preparing asphalt regeneration agent from waste tires. Background technique [0002] With the rapid development of the automobile industry, the amount of waste tires is also increasing day by day. On the one hand, most waste tires cannot be recycled, and the utilization rate is very low, resulting in a serious waste of resources. On the other hand, the long-term exposed stacking of waste tires not only occupies a large amount of land, but also is prone to breeding mosquitoes and spreading diseases after being exposed to the sun and rain, and it is also easy to cause fires, causing serious environmental problems. Therefore, how to recycle waste tires and prevent them from polluting the environment is an outstanding problem that people are facing today. [0003] Asphalt rejuvenator refers to a kind of asphalt rejuvenator that needs to b...
