Abstract

With the implementation and continuous progress of road projects in China, the use of modified asphalt has been recognized in the process of building high-grade roads. At present, its application is more and more common. According to the overall statistics of highway performance testing in China, we find that the aging speed of modified asphalt is faster and faster under the influence of vehicle load and natural factors. In many areas, the aging degree of modified asphalt is very large. This situation will seriously threaten the safety of vehicle driving. The application of recycled asphalt technology is more and more common. In this paper, through the study and analysis of the experimental details, the road performance of the modified asphalt with geothermal regeneration is discussed, and the final conclusion is drawn.
