Abstract

The invention provides a modified asphalt resisting deformation diseases and a preparation method thereof. The method includes: dissolving an emulsifier in water, then adding a stabilizer, transferring the mixture into a colloid mill, then continuously adding matrix asphalt and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide under the action of the colloid mill, performing emulsifying for the first time, adding a modifier, and performing emulsifying for the second time to obtain the modified asphalt resisting deformation diseases. Specifically, the modifier is prepared from tetraethyl orthosilicate, myristic acid, nano boron nitride and zinc, and chromium doped vanadium dioxide as the raw materials through a sol-gel method. According to the invention, through the cooperationof the components of the matrix asphalt and the modification effect of the modifier, the obtained modified asphalt can effectively reduce the occurrence of deformation diseases after being used outdoors for a long time.

Description

technical field [0001] The invention relates to the technical field of traffic pavement materials, in particular to a modified asphalt resistant to deformation and a preparation method thereof. Background technique [0002] With the vigorous development of my country's transportation industry and the continuous improvement of infrastructure, the problems of energy shortage and environmental pollution have become increasingly prominent. Petroleum asphalt is a product of crude oil processing, which is the residue after crude oil distillation. Due to its own properties, it is widely used in road paving. [0003] Asphalt pavement is exposed to ultraviolet light, high temperature, low temperature and heavy load environment for a long time. After long-term use, various diseases will appear, such as deformation, cracks and looseness. Among them, deformation is a very common asphalt pavement disease . [0004] Rutting is a kind of deformation, which refers to the longitudinal stri...
