| 摘要： | In the present study, moisture sensitivity of different aggregates-asphalt binders was evaluated using Surface Free Energy (SFE) approach. Three different asphalt binders: VG 30, PMB 40 and CRMB 60, and two types of aggregates: granite and limestone were selected in this study. The SFE components of the asphalt binders were measured using Wilhelmy plate method, while SFE of granite and limestone aggregates were adopted from the literature. Thereafter, work of adhesion, work of cohesion, work of debonding in presence of water, and energy ratio (ER) were calculated to evaluate moisture sensitivity of asphalt-aggregate system. The results indicate that limestone aggregate had a higher moisture resistant potential with all types of asphalt binders compared to those of granite aggregate. Further, PMB 40 showed better bond with selected aggregates followed by CRMB 60 and VG 30 asphalt binders. It was found that asphalt binder and aggregates types can have a significant influence on moisture sensitivity of aggregates-asphalt binder system. It is expected that the present study would be a positive step in direction of mechanistic evaluation of moisture damage potential of asphalt mixes in India. |
