Characterization of Asphalt Binder Modified by Waste Polythene Bags

Bituminous binder modification is an exercise carried out so as to improve properties of virgin bitumen. In this paper properties of asphalt binder modified by waste polythene shopping bags have been assessed. The binder was modified with varying percentages of waste polyethylene materials (1, 2, 3…..10%) by weight of the binder with 0% serving as control. Modification process was carried out by digesting waste polythene shopping bags in hot asphalt binder to obtain ten samples. Some properties of the modified binder (such as penetration, penetration index, softening point, and ductility) were evaluated for each of the modified samples as well as for the control sample. Observation showed that while penetration and ductility of the modified binder reduced, softening point increased as percentage of polymer material increased. The results showed that modification of bitumen with plastomer like polyethylene caused the binder to become more rigid and less ductile. In the case of penetration index, all the values fell within the limits of -2 and +2 stipulated for paving bituminous binder. The implication of this result is that modification of asphalt binder with plastomer will improve pavement performance especially in tropical regions with high day time temperatures.
