Globally, as the users are increasing, there is a vital competition in Industries to make their products Cheaper, more durable, attractive and easily transportable. For these qualities most of the Industries are using plastics without considering its hazardous nature to the Environment and human beings. Different Types of plastics such as polyethelyene of High and Low density, polypropylene and other polymers are widely used in our daily consumable things such as water bottles, cups, rappers of food, carriage bags, and single used containers. So much use of plastics generates a huge waste worldwide. As this waste is non biodegradable in nature, it is a long lasting headache to avoid its hazardous impacts to ruined human health and degraded Environment. A lot of studies are going on efficient utilization of this waste to convert it into wealth. Highway industry has a big range for different material uses so it can be a smart way to use this waste into the construction of Highways. Studies on properties of plastics gives hint of its long lasting property which can be taken as durability on a positive Note and its presence in oceans from thousands of years shows that even water is impact less on this material which can prove a extraordinary property for Roads. Further on Investigation it was found that optimum percentage of this waste plastics in a particular form can be used for modifying the properties of Bitumen which is known as polymer modified Bitumen. For checking adequacy of required properties of Bitumen that modified bitumen is used in a layer of flexible pavement construction. In this research waste polymer is replaced by bitumen in variation from 2 to 10% at interval of 2% in dense Bituminous Macadam layer of flexible pavement. Marshall Stability test is performed to examine the strength and flow parameter to obtain the optimum doses waste polymer. It has been observed that 4 and 6 % of waste plastic in mix shows better results of Marshall Test as compare to conventional mix.
