Performance evaluation of waste plastic/polymer modified bituminous concrete mixes
This paper describes comparative performance of properties of bituminous concrete mixes containing plastic/polymer (PP) (8% and 15% by wt of bitumen) with conventional bituminous concrete mix (prepared with 60/70 penetration grade bitumen). Significant improvement in properties like marshall stability, retained stability, indirect tensile strength and rutting was observed in PP modified bituminous concrete mixes.
