Utilization of Waste Plastic Water Bottle as a Modifier For Asphalt mixture Properties

Abstract

Utilization of waste material in asphalt pavement would be beneficial in order to find an alternative solution to increase service life of asphalt pavement and reduce environmental pollution as well. One of these waste materials is plastic water Bottles(Polyethylene Terephthalate) (PET) which are being produced in large amount. In this research Polyethylene Terephthalate (PET) was used to investigate the possibility of using waste plastic bottles made of Polyethylene Terephthalate (PET) was used as polymer additives in Bituminous Mixture to overcome the pavement problems . Added five different proportions of (PET) in ( 2%, 4%, 6%, 8% and 10%) by weight of optimum bitumen to prepare the specimens . The tests include the determination of bulk density, stability and flow. Marshall Mix design requires the determination of the percentages of air voids and air voids of mineral aggregate. The results indicated the optimum modifier content was found to be )8 %( for Waste plastic water Bottles(PET) modified asphalt mixture . It is found to give the maximum stability, VFA ,stiffness and minimum flow, Air Voids (AV), compared to the non-modified mixtures and gave better resistance against permanent deformations and better engineering properties
