What is the maximum Liquid Limit & Plasticity Index allowed in earth work in embankment/subgrade soil ?

Question

Accepted Answer

Liquid limit should not exceed 40% and Plasticity Index should not exceed 20% for earth work in embankment/subgrade soil.

Liquid limit and Plasticity Index are important parameters to determine the suitability of soil for construction purposes.
Higher values of Liquid limit and Plasticity Index indicate that the soil is more susceptible to deformation and settlement.
For earth work in embankment/subgrade soil, the maximum allowable Liquid limit is 40% and Plasticity Index is 20%.
If the soil exceeds these limits, it may require additional stabilization measures such as lime or cement stabilization.
Regular testing and monitoring of soil properties is necessary to ensure the safety and stability of the embankment/subgrade.
