Abstract

Karewa soils are extensively spread in the state of Jammu and Kashmir and they've been used as subgrade of pavement layers. Karewa soils are generally muddy soils and are characterized as low bearing capacity materials for flexible pavement layers. When similar soils can not be replaced, its subgrade performance should be increased by several revision ways. In the place, where ground water table is high, the strength of subgrade is negatively affected by humidity infiltration to subgrade and base due to capillary action. The purpose of this design is to estimate the use of low contents of lime in the revision of Karewa soil properties. The main goal of this research is to find the ideal lime dosage for stabilising the readily available karewa soil in the area. The research includes analyses of basic characteristics of soil. Moreover tests are done to find the extent of modification by analyzing the impact of adding different amounts of lime to estimate the extent of revision on MDD, OMC, and CBR of the soil. The experimental examinations shown that there's a tremendous increase in the CBR value of the soil treated with lime, therefore leading to dropped consistence conditions of the sub-base and base courses.
