Analysis of asphalt durability based on inherent and improved performance

The composite performance of modified asphalt is divided into inherent performance and improved performance. The inherent performance of asphalt refers to the original performance of the virgin asphalt. The performance obtained by modifying the virgin asphalt by different methods is referred to the improved performance of the asphalt. In most studies of modified asphalt, researchers pay more attention to how to improve the performance of virgin asphalt at high and low temperatures (i.e., rutting at high temperatures and cracking at low temperatures); however, little attention has been paid to the anti-aging durability of the improved performance. In this project, the macro and micro mechanisms of modified asphalt were compared and analyzed through a series of comparative experiments on the inherent and improved performance of modified asphalt to explore the anti-aging durability of the modified asphalt based on the inherent performance and improved performance at high and low temperatures.
