Bitumen emulsions have recently been taken as one of the most frequently used binders for asphalt surface treatments (AST). Making use of modified bitumen emulsion is necessary to improve AST. Styrene butadiene rubber (SBR) is one of the most commonly used modifiers. The present research study tested the residue of normal and modified bitumen emulsion with different percentages of SBR and X-SBR using ordinary and dynamic shear rheometer methods. The findings revealed that increasing latex SBR led to increasing softening point and needle penetration, so that temperature sensitivity of bitumen residue is reduced. The stiffness of modified bitumen emulsion residue improved significantly by increasing the percentage of SBR. Furthermore, comparing the effect of SBR and X-SBR on bitumen emulsion uncovered that in equal polymer percentage of 6%, X-SBR promoted performance graded for at least one performance grade. Finally, the study is innovative as it dealt with the comparison of high-temperature performance analysis of the impact of polymer percentage simultaneous with that of SBR structure on improving bitumen emulsion. 相似文献

Due to increasing use of styrene-butadiene rubber (SBR) latex in the preparation of polymer-modified bitumen emulsions (PMBE) to improve bitumen-aggregate adhesion of chip seal surface treatments and lack of scientific data on the effect of SBR micro-structure on the performance of the resulting treatment at low temperatures, the Vialit test was conducted. The conventional tests showed that addition of SBR and X-SBR to PMBE reduces bituminous residue (BR) penetration and enhances its penetration index (PI) and softening point. Also, addition of linear SBR latex to bitumen results in an increase in BR ductility and recovery at low temperatures. Meanwhile, addition of the branched carboxylated styrene-butadiene rubber (X-SBR) latex reduces ductility of the corresponding BR. The effect of the performance of bitumen emulsions on aggregate bitumen adhesion in chip seals was investigated using Vialit test. It was found that an increase in SBR latex content in bitumen emulsion leads to an increased aggregate retention; this effect is more pronounced at low temperatures. Comparatively, the addition of X-SBR latex results in a lower bitumen-aggregate adhesion at low temperatures. 相似文献
