Abstract

The invention discloses a novel modifier with basalt fibers for asphalt mixtures and a method for preparing the novel modifier. The novel modifier is made of the basalt fibers and high-adhesion wetting agents. The novel modifier comprises, by weight, 85-98 parts of the basalt fibers, 0-10 parts of film-forming agents A, 0-10 parts of film-forming agents B, 0.1-0.6 part of antistatic agents, 0.2-3.5 parts of coupling agents, 0.1-2 parts of lubricants and 0.1-1.3 parts of modified nanometer SiO2. The method includes mixing the film-forming agents A, the film-forming agents B, the antistatic agents, the coupling agents, the lubricants and the modified nanometer SiO2 with one another to obtain mixtures and stirring the mixtures; wetting and wrapping the basalt fibers and cutting the basalt fibers into short pieces so as to obtain the novel modifier. The novel modifier and the method have the vantages that irritating odor rarely can be generated in modifier preparation procedures; the novel modifier can be added into the asphalt mixtures, accordingly, various road properties of the asphalt mixtures can be effectively improved, the anti-rutting performance and the fatigue cracking resistance of pavements can be improved, and the service lives of roads can be greatly prolonged.

Description

technical field [0001] The invention relates to a pavement pavement material, in particular to a novel basalt fiber asphalt mixture modifier using a direct-throwing high-adhesion modifier and a preparation method thereof, belonging to the technical field of traffic pavement overlay materials. Background technique [0002] With the rapid development of my country's road transport industry, the number of vehicles is increasing day by day, the vehicles are large-scale, and the phenomenon of heavy load and overload is becoming more and more serious. Many pavements have early defects such as rutting, wrapping and even structural damage shortly after completion, which will directly affect the service life of asphalt pavement, and also shows that ordinary asphalt concrete pavement can no longer meet the high temperature requirements of the modern road transportation industry. Requirements for anti-rutting stability, low-temperature crack resistance, and water damage resistance. Th...
