Effect Of Polyvinyl Chloride (PVC) Mixed With Bituminous Materials On Pavement

Abstract

The growth in several types of industries together with population growth has resulted in enormous increase in production of varies type of waste plastic material and it is one of major environmental concerns. On other side, the road traffic and the traffic intensity is increasing; the load bearing capacities of the road should be improved. To deal with the problem, study on use of polyvinyl chloride (PVC) as partial replacement of bitumen is considered in the present work. This paper will help to take care of both those aspects. The main objective of this study was to evaluate laboratory performance of modified bitumen mix using polyvinyl chloride(PVC) dust for flexible pavement to enhance or change in asphalt mix properties. In this study two proportion (8 & 9%) of Polyvinyl chloride (PVC) (PET and HDPE) were introduced in the asphalt mixture with a selected aggregate grading. Amount of laboratory tests such as Penetration, softening point, Specific gravity test and Flash & Fire point test has been carried out by replacing some parts of the bitumen with Polyvinyl Chloride (PVC). The results show that there is an improvement on those properties when compared to normal bitumen. It is expected that using the output of this research, provide an economical solution and minimize the frequency of rehabilitation work by improving the performance of asphalt. It is also expected of substantially reduce volume of environmentally hazardous plastic and environmental pollution. Study recommends contractors and local authorities to confirm using Polyvinyl Chloride (PVC) in asphalt mix with the propose percentage (7% PET and 8% HDPE by OBC weight) to improve the performance of asphalt mix. Moreover, Further studies are needed in various topics related to effective utilization and best incorporation techniques of waste materials.
