Waste Polystyrene is a principal component of urban litter and marine debris. Proper management of waste as become a major concern. Waste Polystyrene is non-degradable and environmentally unfriendly. This study explores the economical use of waste polystyrene as polymer modifier in bitumen. Modified bitumen were prepared by adding 1, 2, 3% waste polystyrene in Malaysia bituminous grades (60/70 and 80/100). The characteristic properties and storage stability of the modified bitumen was evaluated and compared with conventional bitumen and results show a significant increase of 35 and 29% softening point values for 60/70 and 80/100 gradation respectively. There is a 20% reduction in the penetration values for both 60/70 and 80/100 gradation which is an improvement in characteristics of the modified bitumen and there is no significant change in the phase of the modified bitumen after storage. The utilization of waste polystyrene will not only improve bitumen performance but also create a friendly and sustainable environment by creating alternative reuse of the waste.
