A synthesis of theories and mechanisms of bitumen-aggregate adhesion including recent advances in quantifying the effects of water

摘要: A synthesis of research on bitumen-aggregate adhesion is presented within the framework theories and mechanisms established in general field science. An effort made to convey material with perspective introduce terms concepts that would aid understanding associated mechanisms. The ability these place effect moisture a quantitative level considered practical implications discussed. Experimental support included where available. theory (weak) boundary layers, mechanical theory, electrostatic chemical bonding thermodynamic are presented. While elucidates microscopic level, conveniently provides approach based macroscopic measurements. Compatibility different pairs can be assessed if their surface free energies known. In addition, energy combination other properties serves as an important ingredient performance prediction, including stripping potential. Thermodynamic also offers potential quantify pH interface water adhesive bond. authors suggest key quantifying this should sought relationship between electron donor-acceptor bitumen aggregate surfaces.
