The performance of asphalt can be improved by adding styrene-butadiene-styrene (SBS) copolymer and crumb rubber (CR). This paper investigated the influence of the structure and content of styrene-butadiene-styrene (SBS) copolymer on the properties of SBS/CR modified asphalt (SBS/CRMA). These SBS/CRMA were prepared by mixing 90# matrix asphalt, 60 mesh CR powder, and SBS …

According to the theory of molecular design, crumb rubber was grafting activated with acrylamide and then used as asphalt binder modifier. An orthogonal three-factor, three-level test was designed to optimize the preparation process of modified asphalt. Softening point, viscosity, rutting factor, ductility, stiffness modulus and creep speed index were selected as evaluation indicators to study ...

Asphalt Modifiers. Some asphalt cements require modification in order to meet specifications. Asphalt cement modification has been practiced for over 50 years but has received added attention in the past decade or so. The added attention can be attributed to the following factors (Roberts et al., 1996  ): Increased demand on HMA pavements.

Among polymers that may be used in asphalt mixtures, the most used are thermoplastics and elastomers , namely polyethylene based polymers, as well as EVAs, SBS and SBR polymers. According to several authors [5, 6] the use of recycled polymers or waste polymers rather than new is possible and most valuable, which leads to ecological and possibly to economic benefits.
