The Effect and Characterization of Modified Asphalt by Coupling Agent
The study uses distilled water as test liquid, investigates the wettability of modified asphalt with silane coupling agent DB-570 by sessile drop method, measures the contact angel of modified asphalt with different amount of coupling agent based on LB-ADSA model by ADSA software, and also calculates the surface tension of modified asphalt. The study analyzes asphalt membrane by SEM. The results show that the static contact angle of distilled water in the surface of modified asphalt increased with the addition of coupling agent, the adhesion of asphalt and aggregate enhanced after modification, the asphalt membrane become much more complete.
