Bitumen in History

Roads with Plastic waste

All kind of plastic waste collected from the garbage, than sorted, cleaned and shredded to manufacture flakes called as KK Poly Blend. This blend is mixed in the ratio of 8: 100 to the total weight of bitumen in hot mix plant. In hot mix plant, the material is being pumped using specially designed machinery where the blend is sprayed on aggregate at 160 degree Celsius. The plastic gets coated to aggregate and then over coated with bitumen thereby enhancing the bonding strength of aggregate and bitumen. The mix needs to be laid minimum of 100 degree Celsius while asphalting roads for better results.

Technology: The Central Road Research Institute and Center for Transport Engineering, Bangalore University has certified that the addition of 8% K K Poly Blend to bituminous concrete mix will not only increase the Marshall Stability, flow value and comprehensive strength of bitumen but also increases the values of fatigue life and indirect tensile strength by three times when compared with conventional mix. The use of this technology has enhanced the roads' durability, efficiency and performance by 2 folds to that of plastic free roads at a merger additional cost.
