Research ArticleOpen accessIn the keywordsGilsonite Modified Asphalt for Use in Pavement ConstructionAliasghar Akbari Nasrekani, Mostafa Nakhaei, Koorosh Naderi et al.Properties such as durability and moisture resistance of asphalt concrete significantly improve pavement service life. When siliceous aggregate is used, then preventing moisture damage and stripping become distinctly required. Typically, stripping could be prevented by either using antistripping agents or by modifying the binders. The anti-stripping agent achieve its purpose by changing the aggregates' affinity for water through changing the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 3 Apr 2018 · 9,380 accessesView PDFCite
