Gao, Y. (author), Liu, X. (author), Ren, S. (author), Li, Yuanyuan (author), Zhang, Yuqing (author)Surface energy is a key material property and can work as a crucial parameter in various mechanical models to predict the moisture sensitivity and fatigue damage of asphalt mixtures. The calculated surface energy values of the aggregate minerals strongly depend on their surface roughness. Therefore, it is very relevant for accurate...journal article 2023
