Experimental Analysis of Flexible Pavement Structure Using Waste Plastic

Abstract

This paper mainly deals with providing a sustainable and a pro-environmental measure to construct a flexible pavement using thermoplastic modifiers, namely High density polyethylene (HDPE) into the conventional VG 40 grade bitumen sample in different percentage so as to find the proper percentage of blend so as to provide a pavement of good quality with minimal or no maintenance cost and also to reduce the cost of construction and maintain an economy by reducing the percentage of bitumen by replacing it with plastic in shredded form. It also helps in managing a way for disposal of solid waste, particularly Plastic waste and to meet the Millenium Development Goals (MDG). Using of waste plastic such as HDPE or LDPE in shredded form has proven to show promising results both for the environment as well as the pavement construction in term of providing better riding quality and increase in Marshal Stability value and reduction in flow value as compared to conventional bitumen sample.
