Abstract:The adhesion between acid aggregate and asphalt largely determines its ability to resist water damage, the evaluation methods of adhesion between asphalt and aggregate induction was summarized in this paper and detailed study on the impact of boiling method on adhesion, and improved the water boiling method evaluation method. Through the comparison with the standard method, the evaluation process of the improved method was put forward, which could provided the basis for the evaluation of the adhesion between aggregate and asphalt in the special environment.
