Improving Rutting Resistance of Flexible Pavement Structure by Using Waste Plastic

Abstract

On these days traffic is increasing faster rate on roads then various type of defects are produced on road that is rutting, raveling etc A pavement structure have different layers purpose to transfered traffic loads to the sub grade. Rutting is one of the pavement distresses that effects the performance of road pavements. Waste plastic is the type of materials to use for improving the performance of flexible pavements against rutting. In this study utilization of waste plastic water bottles, cold drink bottles, polythene bags, parcel package polythene and films. This waste material clean and shredded small particles (1-3cm) sizes. Aggregate heated 170-200 and mix particles with different percentage (3%, 5%, 7%) properly coated on hot aggregate. This plastic waste coated aggregate is also mixed with hot bitumen. And perform some laboratory test (impact value test, moisture absorption test, marshal value test) on the sample and check the property of rutting resistance.
