Evaluation of the Contribution Rates of Different Phases on Pavement Performance of Cement‐Casting Asphalt Mixture

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Cement‐casting asphalt mixture (CCAM) exhibits excellent antirutting properties and has been widely used to address the severe rutting distress across the world. However, CCAM’s failure mechanism has not been comprehensively understood. To this end, the contribution rates of porous asphalt mixture (PAM), cementitious network, and asphalt‐cement ...

Application of Epoxy‐Asphalt Composite in Asphalt Paving Industry: A Review with Emphasis on Physicochemical Properties and Pavement Performances

open access: yesAdvances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021
One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long‐term performance in service. Thus, epoxy resin was introduced in asphalt paving industry to tackle permanent deformation of asphalt mixtures due to its thermosetting nature.
