In poor subgrade soil areas, pavement construction apt to be relatively expensive. Replacing the poor subgrade soil as a measure taken to improve soil properties cannot always act as an effective economical solution. Taking this as deliberation, with the help of stabilizers similarly, Lime and Crushed sand a trial study has been executed on the soil using three different proportions of lime, crushed sand to illustrate an effective economical solution by the use of subgrade soil chemo-mechanical stabilization. The trial is mainly focused on plasticity, consolidation, compaction and strength characteristics. This study involves trial investigations to categorize the subgrade soils of 3m thickness (which are highly malleable clay cum dusty soils founded in Loni Kalbhor, Pune, Maharashtra). The reports of investigation will be based on the following tests like – Specific Gravity Test (IS 2730-3-1 1980), Sieve Analysis (IS 2720 Part 4 1965), California Bearing Ratio (ASTM D4429-09a), Standard Proctor Test (IS 2720 Part 8 1983), Atterberg Limit of Consistency (IS 2720 Part 5 1985). These trials were conducted to know the properties of the soil like consistency, bearing capacity, comparison of effective methods to improve the bearing capacity using different components to improve the properties of soil. These experiment’s main objectives are to identify the effectiveness of stabilizing the weak soil using crushed sand and lime blend. Examining the blended soil’s physical properties by using Crushed sand and Lime mixture. (CBR) California Bearing Ratio Test under X-ray/Electronic Microscope study and for the blended portion examination the CBR samples test was held. |
