Laboratory evaluation of properties of modified asphalt binder with different types of additives

Abstract This research aims to assess the properties of Polymer Modified Bitumen (PMB) binder prepared with different types additives such as (Waste low density polyethylene (W-LDPE) and crumb rubbers (CR)and Styrene Butadiene (SBS)). Most these are sustainable materials since it is derived from old scrap materials. All above-mentioned (W-LDPE, CR SBS) were added percentages (2, 4, 6 percentage) weight pure asphalt binder. Several tests conducted evaluated improved penetration test, Ductility Softening point Rotational viscosity test well thin-film oven test. The results investigation revealed that, using PMB significantly physical performance asphalt. waste W-LDPE improve contribute in recycling great amount Also, showed that high percentage SBS (6%) increase can affect workability Hot Mix Asphalt (HMA) compared same CR).
