Abstract

The invention discloses inorganic nano-material modified asphalt and a preparation method thereof; the inorganic nano-material modified asphalt is prepared by a modifier composed of carbon nanotubes and nanometer cerium dioxide, and asphalt, wherein the inorganic nano-material modified asphalt comprises the following components by weight: 90-95% of asphalt, 0.1-0.5% of carbon nanotubes, and 4.9-9.5% of nanometer cerium dioxide. The modified asphalt of the invention has good high temperature and low temperature resistance and aging resistance, can prolong the service life of roads, reduce pavement maintenance cost, and is applicable to the paving of engineering such as high-grade roads, airport runways, parking lots, bridges, etc.

Description

technical field [0001] The invention relates to a modified asphalt and a preparation method thereof, in particular to an inorganic nanometer material modified asphalt and a preparation method thereof, and belongs to the technical field of asphalt modification and production. Background technique [0002] Asphalt in organic cementitious materials is an important road paving material, but limited by its own performance, asphalt's high and low temperature performance is unstable. Under the strong sunlight in summer, the asphalt is easy to soften, causing rutting and wrapping; in cold winter, cracks are easy to appear, which seriously affects the comfort of driving on the road and the service life of the road. With the development of transportation in the direction of high speed, heavy load, large flow, and channelization, not only the roadbed is required to be solid and firm, but also the road surface is required to have functions such as wear resistance, high temperature resis...
