To overcome this problem, some methods are studied in this paper to improve the bearing capacity of soil such as the use of Geogrid, soil stabilization using different materials, and proper sub- surface drainage. Soil can be improved by the addition of a stabilizer or excess aggregate. In any case, the traditional undercut & stabilization solution is often costly & always time-consuming. The paper suggests the use of different stabilization methods, plastic coated aggregates and geogrid which helps in increasing the bearing capacity of subgrade soil while greatly reducing the loss of aggregate and cover material into weak, wet or saturated subgrade soils KEYWORDS: Water logged, pavement failure, geogrid, soil stabilization, fly ash, plastic coated aggregate. INTRODUCTION In India road pavement failure is very sensitive and serious issued. We have completed about 70 years of freedom, but till a day we are suffering from road pavement failure, even we have all required manpower and technologies. Especially road pavement failure in waterlogged areas is also a big challenge to the infrastructure ministry of the country. Various experts done lots of research in this field, but this research unable to fulfill the requirement of the roads because expertise studies their respective areas only. Such as geologist studies soil improvement other studies, drainage and someone focused improvement in pavement material. Their study unable to give whole pavement design consideration required for ideal road pavement in waterlogged areas. This results in increasing life cycle costing of the road project. In this paper I am doing study of all the research paper and available methods and divide them into three categories as soil improvement, drainage solution and pavement design. The aim of this paper is to make a comparative study of all methods, practices in different areas and find out ideal design consideration for road pavements in waterlogged areas. LITERATURE REVIEW The technique of stabilizing the soil with sand and cement is being carried from long time. Mixing Portland cement, sand and pulverized black cotton soil with the optimum moisture content and compacting the mix to attain required density. The material obtained by mixing soil, cement and sand is known as cement sand soil. Cement in the range of 2 to 5 percent brings remarkable improvement in the engineering characteristics of B.C. soil. Similarly, increasing proportion of sand as stabilizer also improves the properties of soil. (Mrs. Neetu Ramteke, June 2014) Fly ash is having good cementing and pozzolanic properties. Use of fly ash in road construction on the black cotton soil is an excellent technique of killing two birds with one stone meaningful utilization of industrial waste and stabilizing this high expansive black cotton soil.
