Central Road Research Institute, New Delhi (R)

 

Present Status and Progress
This project is a sub project of the Network project entitled New and Improved Road Technology being carried out in collaboration with Central Institute of Plastic Engineering and Technology (CIPET), Chennai
Six samples of polymeric sheets of varying thickness were sent by CIPET, Chennai under the collaborative network project. Out of these, two samples were shredded into small pieces. Appropriate quantity of shredded samples of polymeric sheet was added to hot melt 80/100 bitumen to assess the feasibility of these materials to pack the bitumen. Polypack modified bitumen were tested for their physical properties as per BIS 15462. The shredded film is completely dispersible in bitumen in hot melt condition whereas it gets separated from bituminous phase at ambient temperature. Further work is under progress.
