Theses and Dissertations
This study investigated the effects of asphalt oxidation and testing temperature on moisture damage in asphalt mixtures, using AASHTO T283 and Surface Free Energy (SFE) testing. The study assessed the impact of three asphalt binder grades (PG 64-22, PG 76-22, and PG 52-34) and three test temperatures (ALT, AIT, and CIT) on the susceptibility to moisture damage. Additionally, three oxidation levels (OTC, STOC, and LTOC) were evaluated to determine the optimal level of oxidation and testing temperature for AASHTO T283 to detect moisture damage. Load-displacement curve parameters and IDEAL-CT were analyzed to better understand the effects of oxidation and moisture …
