Abstract: This paper is a review of research that has been carried out on the asphalt modifiers for road paving and maintenance applications. The application status of elastomers, thermoplastic polymers and thermoplastic elastomers, notably the specific polymers that are used widely including styrene-butadiene-styrene (SBS), styrene-butadiene rubber (SBR) and ethylene vinyl acetate (EVA), are elaborated. Many studies have shown that, if one modifier is grafted with a monomer or blended with the other modifier, an improved performance can be achieved when it is used for modifying the asphalt. From an application point of view, various modifiers with higher performance and used for chemical modification upon asphalt would be developed in China.
Keywords: Modifier; Modified Asphalt; Styrene–Butadiene–Styrene; Styrene–Butadiene Rubber; Ethylene Vinyl Acetate
