In India, flexible pavements with bituminous surfaces are widely used. Due to increased traffic intensity of roads, overloading of commercial vehicles and temperature variation of pavements due to climatic changes leads to formation of various distresses like rutting, shoving, bleeding, cracking and potholing of bituminous surfacing. Due to high temperature, bitumen becomes very soft in summer and brittle in winter. Also, in a developing country like India, roadway construction is taking place at a very high pace which require large demand of construction material that too eco-friendly and economical. Several Studies have revealed that properties of bitumen and bituminous mixes can be improved/ modified with addition of certain additives and the bitumen premixed with these additives/modifiers is known as “modified bitumen”. The present study aims for use of modified bitumen by using plastic waste for road construction. The paper includes details of methodology of using modifiers in bitumen and aims to provide highway construction in a eco-friendly and economical way. The modified bitumen mix shows better binding property, stability, density and more resistant to water.
