The measure of plastic in the solid waste generated is increasing due to increase in factors such as urbanization, various development activities and changes in life style of humans which is leading to an unrestricted scattering on the landscape. Thus the disposal of these waste plastic has become a severe issue globally due to their non-biodegradability nature. Another area of concern is the deteriorating quality of roads due to the increase in traffic and their lower resistant’s to withstand adverse climatic conditions. Studies are being carried out to develop suitable alternatives for providing good, conventional road constructional materials for providing eco-friendly roads which have good design life. In this work, autoclaved medical plastic waste in the form of shredded syringes used in road construction is tested. The main objective of this work is to study how to use shredded Biomedical Plastic waste (BMPW) in Bituminous Mix and to compare the performance of the aggregate and bitumen when modified with bio-medical plastic waste. The results from the case studies showed improved properties for Plastic Coated Aggregate when compared to normal aggregates. There by showing that by using biomedical waste in bituminous road construction could bitterly change the quality of road and also the design life of bituminous roads by improving their properties.
