Abstract:Reclaimed asphalt pavement (RAP) has been used in micro-surfacing mixtures with good promise and improved sustainability. However, no systematic study has been conducted to analyze the chemical components of the RAP micro-surfacing mixture when blending virgin binder with RAP binder, and to confirm the reasonableness of using RAP micro-surfacing mixtures. Based on a gap-graded method, this paper explored the chemical properties of RAP micro-surfacing mixtures using attenuated total reflectance–Fourier transfor… 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.
