Modification of asphalt binders by polyethylene-type polymers

Dariusz Brożyna , Karol Kowalski


This investigation tested the effects of asphalt binder modification, using polyethylene-type polymers. During the research, five different polymers were used: HDPE, LDPE, LLDPE, copolymer EBA (ethylene/butyl acrylate) and terpolymer EBM (ethylene/butyl acrylate/maleic anhydride). Those polyethylene-type polymers were used to in-lab modif ication of 50/70 raw unmodified road bitumen. Modified specimens were tested in terms of penetration, softening temperature and elastic recovery. Samples were aged using the Rolling Thin Film Oven Test procedure. The gathered data suggest that addition of polyethylene-type polymers to the asphalt binders reduces penetration, and increases softening tempera ture. In terms of elastic recovery only terpolymer EBM presented significant improvement, reaching a 75% relative elastic recovery
