K K Poly Blend is a polymer blend made out of plastic carry bags/packing material. The K K Poly Blend is cheaper than all existing bitumen modifiers and is the best binding agent for bitumen.
Process Adopted: We have devised an end to end process for collecting all kinds of plastic waste from the garbage, its sorting, cleaning and shredding to manufacture flakes called as KK Poly Blend; using exclusively patented in-house manufactured machineries for this purpose. This blend is mixed in the ratio of 8: 100 to the total weight of bitumen in hotmix plant. In hotmix plant, we pump the material using specially designed machineries 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. Few of the field study reports are briefed below.
Project Experience: We take the pride to share that so far 2000 km of road stretch has been laid in Bangalore reusing 8000 tons of plastic waste retrieved from garbage. The Indian Road Congress has published guidelines of plastic waste roads in the year 2013. Many states like Rajasthan, Maharashtra, Manipur and Goa have come forward to replicate the technology after witnessing Bangalore's experience. Even other countries like Sudan, New Zealand, and sierra are showing interest in implementing this technology in their local areas.
