Abstract:

The life of road depends on strength of the subgrade soil and traffic density. The subgrade soil is not uniform throughout the alignment of the road. Generally the poor subgrade soil having soaked California Bearing Ratio (CBR) value less than 2% is replaced by good quality subgrade material. This paper deals with the improvement in various properties of subgrade soil by using soil stabilizer and locally available poor materials. The additive like RBI Grade 81is used to improve the properties of subgrade soil. The cost of construction of road increases, if only RBI Grade 81 is used as a stabilizer. The CBR value of subgrade soil can be improved by using moorum with RBI Grade 81and cost of construction can be reduced to certain extent. From CBR test, it is found that the CBR value of soil is improved by stabilizing soil with 1% and 2% RBI Grade 81. The various mixes of clay and silt soil with RBI Grade 81 for the different proportions were tested for maximum dry density (MDD), optimum moisture content (OMC) and soaked CBR value.
