Abstract: Transportation is an essential component for the infrastructure of all the countries. The economy and economic status of any country is determined by its network of roads, railways, waterways, airways, pipes and ports. . In the northern areas of our country, roads are the most important source of connectivity. Due to cold weather conditions which include factors like snow, rain, frost, and these roads suffer excessive damage and thus hamper the movement of people as well as goods across these parts of the country. To improve the conditions of the road connectivity in such areas huge amount of money is being invested, but the end results don’t come as satisfactory as they should come. To prevent the damage to these roads by such factors no particular method has been developed. Use of plastic in bituminous mixes can be of importance in curbing the excess damage to roads in cold weather conditions. Waste plastic roads have been used in some parts of the country with a varying degree of success. Waste plastic roads have various advantages over normal roads which can be of great importance in these parts of the country. Keywords: Subzero Temperature, roads, design, waste plastic, bitumen.
