The Bangalore International Airport Limited’s (BIAL) idea to polymerise the roads inside the airport campus has cut costs and made them more durable.
Technical experts at the Kempegowda International Airport said the cost went down by Rs 60,000 for a kilometer, with 3.5 metres and 40 mm thickness paved with waste plastic and bitumen mixture.
“There are several benefits of polymerising the roads,” explained B V Kiran Kumar, associate professor, Government Sri Krishnarajendra Silver Jubilee Technological Institute.
“One is that the quantity of bitumen is reduced and substituted with waste plastic in the aggregate (mixture). This would reduce the construction cost. Plastic is an excellent binding material, offering flexibility to the roads.
