A PROCESS FOR THE PREPARATION OF WASTE PLASTIC MODIFIED BITUMEN USEFUL FOR RUT RESISTANT AND WATER RESISTANT BITUMINOUS MIX FOR ROAD CONSTUCTION

摘要

The present invention relates to a process for the preparation of waste plastic modified bitumen useful for rut resistant and water resistant bituminous mix for road construction. More particularly it relates to utilisation of waste plastic bags for modification of bitumen to obtain Polymer Modified Bitumen used for Construction of Roads. The bituminous mixes prepared using waste plastic modified bitumen has higher resistant to rutting compared to other modified bitumen and conventional bitumen. In the process powdered plastic waste 2 to 8 wt% of bitumen are added in standard bitumen, mixture is stirred at 1000 to 3000 rpm for 25 to 40 minutes and further 0.15 to 0.25 % of hydrogenated tallow is added for better homogeneity of blend to obtain the desired product
