The addition of polymers in bitumen improves the deformational stability and durability of bitumen. In the present study, the effect of waste Low Density Polyethylene (LDPE) and Polypropylene (PP) obtained from waste carry bag, on various properties of bitumen such as penetration, ductility softening point 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%, 6%, 8%and 10% percentages in 60/70 penetration grade bitumen and its effect on different properties of bitumen are evaluated. The result of experimental study shows that there is significant improvement in the properties of bitumen due to LDPE and PP modification.

About 80% of the produced bitumen is used for pavement construction. The quality of the binders can be improved by their modification with polymers and rubber obtained from waste tyre. At the same time, utilization of waste rubber would solve a serious environmental problem. In the present study effects of Crumb Rubber (CR) obtained from waste tyre on physical and strength properties of 60/70 penetration grade bitumen are evaluated. The crumb rubber modified bitumen is prepared in the laboratory, taking CR content 2%, 4%, 6%, 8% and 10% by weight of bitumen. It is found that the physical and strength properties of the binder are improved due to the modification by waste tyre rubber.

Unmodified bitumen cannot perform better with the range extreme minimum and maximum pavement temperatures. The polymers commonly used to modify the bitumen are ethylene vinyl acetate (EVA) styrene butadiene styrene (SBS). The aim this study to compare the performance of EVA modified bitumen with the bitumen modified by waste low density polyethylene (LDPE), polypropylene (PP) obtained from waste carry bags and waste tyre rubber (CR) to encourage the use of waste polymer whose disposal is big problem today, in place of costly virgin polymer. From the experimental study, it was found that waste polymers are also effective in improving the properties bitumen as that of virgin polymer.

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 bi...

About 80% of the produced bitumen is used for pavement construction. The addition of polymer in bitumen improves pavement durability and lower life cycle costs. In the present experimental study, properties of waste tyre crumb rubber (CR) and ethylene vinyl acetate (EVA) modified bitumen is evaluated. The waste tyre of cars is crumbed and used as an additive in bitumen; the waste tyre polymers and EVA are added in various percentages, like 2%, 4%, 6%, 8% and 10% by weight in 60/70 penetration grade bitumen, and its effect on different properties of bitumen is evaluated.
