Evaluation of the properties of modified local asphalt binder by using styrene butadiene rubber (SBR) or low-density polyethylene (LDPE)

The influence of styrene butadiene rubber (SBR) or low-density polyethylene (LDPE) polymers on the characteristics local asphalt binder was analyzed to characterize rheological properties. results indicated that SBR LDPE increased softening point. point enhanced by around 35% when 9% used in comparison unmodified asphalt, while there a 15% increment used. also decreased penetration rate. decreases 36% is compared neat significant 89% Additionally, employed, ductility rose roughly 73%, but 64% less seen utilized. Finally, addition additive has improved index, thus reducing temperature sensitivity. Due said above, and are practical promising modifiers will be useful enhancing performance straightforwardly efficiently.
