Low Density Polyethylene Modified Dense Graded

Abstract — This paper presents the use of waste polythene carry bags in flexible pavement construction. Reclaimed plastic waste derived from low density polyethylene (LDPE/PW) carry bags from kitchen waste and plastic bottles have been used as additive in flexible pavements. Purposes of using above materials are to utilize environmentally unacceptable waste material and to develop a better material mix to resist increased traffic load and pressure resulted in cracks in the pavement surface. In the present study the plastic waste was cleaned and cut into a size such that it passes through 2-3mm sieve using shredding machine. In this study Dense Bituminous Macadam (DBM) mix has been prepared by using plain bitumen as a control specimen and bitumen mixed with low density polyethylene (LDPE/PW) in different proportions such as 2, 4, 6, 8, 10 and 12% by weight. The Marshall Stability tests were conducted on control and modified DBM mixes. It has been observed that the plastic waste modified bitumen mix show better binding property, stability, density and more resistant to water. Hence, the present technology will not only strengthen the road construction but also increases the road life as well as will help to improve the environment
