TL;DR: This review presents a comprehensive summary of the state-of-the-art investigations concerning the self-healing mechanism, model, characterization and enhancement, ranging from asphalt to asphalt pavement.
Journal ArticleDOI
Intrinsic temperature sensitive self-healing character of asphalt binders based on molecular dynamics simulations
TL;DR: In this paper, the authors used the molecular dynamics simulation to explain the microscopic process of asphalt self-healing and investigate the influence of temperature on the selfhealing capability of asphalt binders.
Journal ArticleDOI
Formulation and aging resistance of modified bio-asphalt containing high percentage of waste cooking oil residues
TL;DR: In this article, a bio-asphalt with high percentage of WCOR derived from esterification reaction for biodiesel was used for making bio-approximate asphalt, which is a potential substitute for petroleum asphalt.
