Stabilization of Subgrade Soil for Flexible Pavements Using Calcium Lignosulfonate and Granite Dust

  • Abstract:
  • Soil forms the fundamental base for all civil engineering structures and must possess adequate strength to safely support the loads imposed upon it. However, in many locations the naturally available soil is weak and incapable of resisting these loads effectively, which may lead to settlement or structural failure. In such situations, soil stabilization becomes necessary to improve the engineering properties of the soil. Various soil stabilization techniques have been reported in the literature, including chemical stabilization and lime stabilization. However, some of these methods may adversely alter the chemical composition of the soil and may not always be environmentally suitable. In the present experimental study, clay soil samples were tested both without additives and with additives to evaluate their engineering characteristics. Laboratory tests were conducted to determine the Optimum Moisture Content (OMC), Maximum Dry Density (MDD), California Bearing Ratio (CBR), and Plasticity Index (PI). The results obtained from these tests were used to assess the improvement in soil properties due to stabilization.
