Abstract

In this research, by using mechanical and thermodynamic methods, the effect of surface coatings of aggregates with crystal calcium carbonate powder on the moisture sensitivity of asphalt mixtures has been evaluated. The results show that the indirect tensile strength of the modified specimens has been increased. as Also, the result of SFE method indicates that, with aggregate surface modification, their acidic and basic components respectively have been reduced and increased. Due to these changes, the adhesion between aggregates and bitumen (which is an acidic substance) increase. In addition, the amount of released energy in the presence of moisture has been reduced for modified specimens, which indicates a reduction in the tendency of the mixture for stripping.
