| dc.description.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.
