There are thousands of industries growing in many countries like in India, in which industrial waste become a serious problems. In those industries paper mill industry is one of them, which produce thousands of tones waste material every year. Utilization of this waste material in required civil engineering area can be proved a good additive in construction. Waste Paper Sludge (WPS) is a lime sludge wastage material come from Paper Industry generally dumped into sites around the Industries. 2 %, 4 %, 6 %, 8 % and 10 % Waste Paper Sludge (WPS) added to the soil and conducted test for analysis of strength properties of soil. Laboratory experiments results showed that 6 % is the optimum percentage of Waste Paper Sludge (WPS) which is mixed in the soil for obtained higher strength. In civil engineering construction like Railway lines, Highway Network, Airport Runways etc are required a good strength of soil embankment, where Waste Paper Sludge (WPS) become a good additive for improving strength of soil. Key Words: Compaction, Compressive Strength, Road Pavement, Strength Development, Waste Paper Sludge (WPS). 1. INTRODUCTION In Civil Engineering Construction like Railway lines, Highway Network, Airport Runways etc are required on Soil Embankment for construction. There are various processes like chemical, mechanical, biological or combined method in order to improve soil properties such as compressibility, strength, permeability and durability. Industrialization and urbanization is a major area of every country which is growing up in each year. Industrialization is one of the areas of each country in which numbers of industries are increasing year by year. These industries manufacture many items and also produce thousands of tones waste material. Paper mill Industries is one of them which create waste material every year. Urbanization is the required for the growth of country resulting developing the lives of its country people. Civil construction is also a part of urbanization. Sometimes site engineers faces the problems in the field due to poor the strength of soil. Conventionally different materials like cement, lime and fiber etc are used to mix with soil for improving the strength of soil. These materials increase the cost of construction, results an uneconomical construction. In many industries waste materials are available which is not recycled yet for their utilizing purpose. Paper mill industries are one of them in which Waste Paper Sludge (WPS) is a waste materials dumped around the industry premise. This waste material also covers a large area to landfill. When this waste material dried in presence of sun light creates dust which leads to the air pollution in nearby areas which also affects human health. 2.
