Abstract: 

Effect of the blends of different polyethylenes (LDPE=low-density polyethylene, LLDPE=linear low density polyethylene and HDPE=high density polyethylene) and rubbers (PBR= polybutadine rubber, SBR=styrene butadiene random copolymer, NR=natural rubber and SEBS=styrene-ethylene-butylene-styrene block copolymer) on bitumen properties was investigated. PBR-PE blends form a physical network in bitumen medium, whereas their SBR, NR and SEBS counterparts do not. The properties of the resulting bituminous blends are comparable with those of SEBS blends. LLDPE shows a higher rate of effectiveness on bitumen properties as compared with other polyethylenes. SBR blends show a better elastic recovery and film forming properties. Addition of heavy vacuum slops (HVS) oil into the ternary blends of rubber-PE-Bitumen results in rubber inclusions volumes. The rubber swelling increases as HVS oil concentration increases. HVS oil concentration could be adjusted depending on the designed performance grade (PG). SBR-PE blends found to be the most effective blends on bitumen properties.
