This study investigated the effect of seven healing agents on crack healing ability of long-term aged asphalt and its mortar. Different healing agents including sunflower oil, aromatic oil, bitumen emulsion, and maltene-based ...

This study reports the long-term crack healing effect of five healing agents (HAs) applied on fractured semi-circular bending test samples of AC-13 asphalt mixtures. A multiple fracture-rehealing test was adopted to simulate ...

This study investigated the crack healing ability of aged and unaged AC-13 basalt asphalt mixtures using five healing agents. Notched semicircular asphalt mixtures were cracked and healed using the healing agents and the ...
