EXPERIMENTAL ANALYSIS OF BITUMEN WITH HDPE AND PVC FOR USE IN FLEXIBLE PAVEMENT

Civil engineering

Bitumen is a binding material mostly used in construction projects like road surfacing, airports, parking lots etc. This is primarily because of their excellent binding characteristics and water proofing property The study results shows that rheological properties like Penetration, Ductility of waste plastic and PVC modified bitumen decreases with increase of these contents. While Softening point, increases with increase in polymer contents in bitumen. The Marshall stability test results shows that the polymer increases the stability values of the compacted mixes with increasing. The polymer content in the bitumen up to optimum level (i.e.4%). The values obtained in the Marshall stability test show increasing pattern up to 4% of PVC and waste plastic content, whereas the density of the compacted mixes slightly decreases with the increase of polymer contents in the bitumen. This paper presents a research study the behavior of BC mix modified with waste polythene and PVC. Various percentages of these polymer are used for preparation of mixes with a aggregate grading as given in the IRC Code.
