Resilient Modulus of Lime Treated Expansive Soil

Bhuvaneshwari, S. / Robinson, R. G. / Gandhi, S. R.

Abstract Subgrade soils play a major role in the proper functioning of pavements. They are subjected to repeated loads due to traffic and often subjected to moisture ingress during monsoon seasons. If the subgrade is expansive in nature, lime stabilization is commonly adopted to mitigate swelling and shrinkage. However, the behavior of lime treated expansive soil under the cyclic loading and effect of moisture ingress is not yet fully understood. The subgrade is generally characterized by the parameter Resilient Modulus (MR), which is determined under laboratory conditions. Considering these issues, an experimental study is attempted to compare the resilient modulus (MR) and permanent strain values of untreated and lime treated soil. The comparison is made based on different percentages of lime and curing period. The test results are finally used to analyze the behavior of lime treated soil in their in-situ stress states.
