ROAD made from waste plastic...!

11:03 AM    3 comments



1. Plastics waste (bags, cups, thermo Cole) made out of PE, PP and PS cut into a size between 2.36mm and 4.75mm using shredding machine, (PVC waste should be eliminated).

2. The aggregate mix is heated to 165°c (as per the HRS specification) and transferred to mixing chamber.
     Similarly the bitumen is to be heated up to a maximum of 160°c (HRS Specification) to have good binding and to prevent weak bonding. (Monitoring the temperature is very important).

3.  At the mixing chamber, the shredded plastics waste is to be added. It get coated uniformly over the aggregate within 30 to 60 seconds, giving an oily look.

4. The plastics waste coated aggregate is mixed with got bitumen and the resulted mix is used for road construction. The road laying temperature is between 110°c to 120°c. The roller used is 8-ton capacity.

      If the plastic is not cut into pieces it can't be mixed with soil but here plastic bags were cut into small pieces (2.36mm and 4.75mm)
