The rapid growth in plastic consumption and its improper disposal have led to severe environmental challenges. The disposal of waste plastic poses significant environmental threat, contributing to both pollution and climate change. Recycling and reusing plastic waste have emerged as viable solutions, and the application of LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene) waste in bituminous road construction has gained significant attention. Bituminous mixes gain strength and improved properties when plastic waste is used for paving roads. Poly-ethylene, polystyrene, and polypropylene are the types of waste plastic utilized. The shredded waste plastic is coated with aggregate, mixed with hot bitumen, and used to construct pavement. The pavement's durability increases and reduces flaws, such as, ruts, corrugations, potholes etc. This paper reviews published literature and comprehensively analyses existing research on the compatibility and effectiveness of incorporating LDPE waste plastic on Indian roads. The paper brings out literature on various methods of utilization, performance enhancements, environmental benefits and identifies a research gap in sustainable road infrastructure development which can create a very big shift in clearing or even completely avoiding LDPE in landfills and waste dumps
