Abstract
The performance and serviceability of pavements are highly dependent on the engineering characteristics of the underlying subgrade soil. Weak or problematic soils, if left untreated, often lead to premature failures such as rutting, cracking, and differential settlement in highway pavements. In India, expansive and low-strength soils are commonly encountered, necessitating soil improvement techniques for safe and economical road construction. Soil stabilization, particularly with cement, has emerged as one of the most effective methods for improving soil strength, reducing plasticity, and enhancing durability. The present study focuses on the experimental evaluation of cement-stabilized soil intended for highway subgrade applications.The natural soil used in this study was classified as clay of low to intermediate plasticity (CLCI) in accordance with IS 1498:1970, with a liquid limit of 35.22%, plastic limit of 20.61%, and plasticity index of 14.61%. The soil exhibited a free swelling index of 26.88%, indic
