Abstract. Polymer modified bitumen is emerging as one of the important construction materials for flexible pavements. The addition of polymers in bitumen improves the deformational stability and durability of bitumen. Also Montmorillonite nanoclay has been successfully used as additive in polymer to significantly improve the thermal stability and mechanical properties. The present study, the effect of waste low density polyethylene (LDPE), polypropylene (PP) obtained from waste carry bag, crumb rubber obtained from Waste tyre (CR)and nanoclay (MMT) on Marshall stability have been evaluated. Waste plastics, whose disposal is a matter of concern can be used successfully to modify the bitumen, these waste polymers are added in 2%, 4% and 6% whereas nanoclay is added in 1,2 and 3 % in 60/70 penetration grade bitumen and its effect on stability and flow of bitumen are evaluated. The result of experimental study shows that there is significant improvement in the Marshall Stability of bitumen due addition of waste polymer and nanoclay.

Key Words: Waste Plastic, waste tyre, modified bitumen, Marshall stability
