Problems solved by technology

However, these two maintenance methods have great disadvantages, which are not only not conducive to environmental protection, but also waste a lot of manpower and material resources, and the maintenance period is long, which is easy to cause traffic jams
On the other hand, the improvement of asphalt processing technology often means the replacement of equipment, which requires more manpower and material resources

Abstract

The invention discloses a graphene asphalt additive which is composed of the following components: carboxylated graphene oxide, gamma-(2,3-epoxypropoxy)propyltrimethoxysilane, alkyl glycoside, polyvinyl alcohol, borate, polymethyl methacrylate, a styrene block copolymer, polyurethane and waste rubber powder. The invention also discloses a preparation method of the graphene additive. According to the additive disclosed by the invention, on the basis of an existing asphalt production process, various physicochemical indexes of asphalt can be improved in a direct adding manner.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a graphene pitch additive and a preparation method thereof. Background technique [0002] Highway construction is an important indicator to measure the development of the national economy. In recent years, my country's highway construction has made great progress. In all highway construction mileage, asphalt pavement accounts for the vast majority. However, in the face of a series of current situations such as the gradual increase of highway traffic flow in our country, the increase of vehicle speed, and the increase in the number of heavy loads, this pavement structure is the first to be destroyed. It is the surface functional layer, which will not only produce cracks, looseness, cracks, pits and other diseases, but also seriously damage the anti-skid performance, smoothness and noise performance of the road surface, and the driving safety and comfort cannot be guaranteed. How...
