-With increased transportation, waste tire rubber accumulation becomes a major environmental concern. The use of crumb rubber, recycled tire rubber is considered as an additive in bitumen modification for road pavement and economic disposal or tire rubber. Although, crumb rubber modified bitumen shows excellent performance properties due to its elastic nature but meanwhile storage stability of crumb rubber modified bitumen (CRMB) is still an issue due to poor dispersion of crumb rubber particle in bitumen, which affects the performance of road pavement. Keeping these issues in mind, we have doped various long chain amines in CRMB to improve its storage stability and physical and rheological properties CRMB.
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.
