Abstract:A method to investigate the effectiveness of interlay systems in hot-mix asphalt (HMA) overlays to retard reflective cracking is introduced. Significant research has been conducted on developing techniques to reduce reflective cracking in HMA overlays. Many interlayer systems have been used in the field; some showed no structural or economical benefits, while others could reduce reflective cracking in the short term. However, long-term and quantitative benefits for many of these techniques have not been realiz… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
