The Karnataka State Pollution Control Board (KSPCB) ordered the Karnataka State Highways Improvement Project (KSHIP), the Karnataka Rural Infrastructure Development Limited (KRIDIL) and the Karnataka Public Works Department (KPWD) to make compulsory use of plastic waste in the construction of roads, in accordance with the Indian Road Congress. (IRC).
“We are one of the first states in the country to take this step towards effective plastic waste management. KSPCB is making efforts for the scientific disposal of plastic waste in terms of disposal in cement factories for efficient recycling processes and one of these scientific disposals is also using it in road construction. Many developed countries recycle plastic waste to make a variety of products, including some used in heavy construction such as railway ties, road buildings and paving stones, ”said KSPCB member secretary Srinivasulu K. Indian express.
IRC says processed plastic waste is shredded to a particular size and then mixed with hot bitumen. This mixture is used in road construction. The laying temperature of the road should be between 120 and 160 degrees Celsius. Experts point out that one of the advantages of using waste plastic as a modifier in the binder is the higher resistance to warping and water-induced damage.
The copy from the management of the KSPCB reads: “Studies have revealed that plastic waste has great potential for use in bituminous construction, as its addition in small doses, around 5-10% by weight of bitumen. , helps to significantly improve the stability, the resistance of Marshall. , fatigue resistance and other desirable properties of the bituminous mixture, which improves the longevity and performance of the pavement. The use of plastic waste thus contributes to the construction of green roads.
The Ministry of Environment, Forests and Climate Change notified in 2016 that local bodies will encourage the use of plastic waste (preferably plastic waste which cannot be further recycled) for road construction in accordance with the ‘IRC.
