| Abstract: | Based on the classical theory of modern colloid chemistry,the mechanism of aging and regeneration of aged asphalt are analyzed.Through recovery tests on asphalt aged for different periods,the performance of aged asphalt recovered with a new type of asphalt regenerant is analyzed and evaluated.The results indicate that the new asphalt regenerant regenerates aged asphalt and recover the road performance of aged asphalt mixture effectively. |
