Ponda, Goa plans to make roads of plastic made from polymer-blended bitumen, making it the first in the state to construct 'plastic roads'. This material shows higher softening point, lower penetration point and better ductility.
The Central Pollution Control Board (CPCB) plans to bear 50% of the cost of such roads, while the remaining 50% will have to be borne by the concerned municipal body in the state. If the concept of 'plastic roads' is successfully implemented in Ponda taluka, it may well be followed by other municipal bodies around the state
The 'plastic roads' involve plastic waste, including disposable plastic being shredded and mixed with bitumen at a high temperature of around 160 degrees centigrade in the mini hot-mix plant, which in turn gives the plastic mixture a better binding property on softening. This polymer-coated aggregate with bitumen is a better material for road construction, in terms of strength and resistance to rainwater.
