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.
