Research on Influence Regularities and Evaluating Parameters of Adhesion Performance between Aging Asphalt and Aggregate

Abstract:

In the paper, the method of prolong aging time in oven was adopted to get different aging degree asphalt, such as base asphalt and modified asphalt. Firstly, the mass loss percent during water cooking and adhesion grade were tested to evaluate the adhesion property. Then, the influence regularities of adhesion property were analyzed due to asphalt aging. Finally, the relativity between mass loss percent and adhesion grade was carried out. It is found that adhesion grade is falling, and mass loss percent is increasing with the adding of asphalt aging degree. And the study result also proves that modified asphalt has better adhesion performance than base asphalt. The two evaluation parameters have stabilization relativity. The mass loss percent is advised to use to evaluate adhesion performance for better objectivity.
