Polymer coated plastic Roads laid on Kurnool district Roads

Polymer coated plastic roads are laid on NH 44 at a cost of Rs 1.25 crore from Veludurthi Highway Point to Mallepalli in Kurnool District.

Kurnool: The District Panchayat Raj officials of Kurnool have unanimously opted for plastic roads to be laid in the district. Plastic and tar bonds well together because both are petroleum products.  Both the products contain the most cost effective combination that is eco-friendly too for roads laying.

Scientific results in their favor, engineers says that plans are afoot to construct plastic roads across the district and  Plastic is the waste material which can be turned into raw material for laying of roads and this would be the best solution to bury the waste material on road with tar and bitumen.

Plastic roads laid on kurnool district

Taking a cue from their Telangana counterparts who had laid half a kilometer road with plastic in Hyderabad, Kurnool district is going to be an innovator in this technique in Andhra Pradesh. Already Nellore district had experimented with plastic roads in Andhra Pradesh. Now  Kurnool district, and other districts in the state with concrete plans to use plastic road laying technology. On National Highway 44 at a cost of Rs 1.25 crore, a 2km stretch was laid from Veludurthi Highway Point to Mallepalli.

Kurnool Executive Engineer Venkata Ramana Reddy and Panchayat Raj Superintendent Engineer S. Subbarayudu jointly checked the site and said the result was very encouraging. They said the raw materials are imported from Tamil Nadu which cost Rs 45 per kilometer and 2 tonnes of plastic scrap was used in laying the road. They stated that, the plastic mixture was available near Alur in the district. Two more roads

They also stated that there are two more proposals to lay plastic roads between Yemmiganur-Adoni Main road to Venkatagiri at a cost of Rs 72 lakh over a stretch of 1.4 kilometres and the other one is planned between Kadimetla in Yemminganur and Siralladoddi at a cost of Rs 1.10 crore to lay a stretch of 3.5 km. The project was undertaken by  Central Pollution Control Board with an engineering college in Tamil Nadu to assess and evaluate the performance of polymer coated roads.

 Observations on plastic roads include:

1) A high percentage of polymer coating increases the binding strength of the mixture.

2) The stretches in the roads have been found reasonably strong.

3) The index values of these plastic roads are nearly 3,000 mm/km, which indicate a good surface evenness.

4) Even after four years, the plastic tar roads did not exhibit any potholes, rutting, ravelling or edge flaw,

5) The extracted bitumen showed almost near value for Marshall Stability. The road has good skid resistance and texture values.
