Weak clayey soil can cause premature failure in subgrade so their removal or proper treatment is necessary for the efficiency of structure. Soil stabilization is an excellent choice and economical in many circumstances for treatment and proper behavior of weak subgrade soil as recommended by many researchers. Lime is the oldest and well known additive for stabilization of many type of soils. This paper presents geotechnical investigation of low plastic clay soil being used as subgrade stabilized with lime. The low plastic clayey subgrade soil was stabilized with different percentages of lime and results show that soil can be satisfactorily stabilized with the addition of 6% lime. The Atterberg’s limit, compaction characteristics and strength tests including unconfined compressive strength (UCS) and California bearing ratio (CBR) tests were performed. Results indicate that addition of lime reduce plasticity index. An increase in OMC was observed with the decrease in maximum dry density (MDD). CBR and unconfined compressive strength of soil (qu)values improved significantly with the addition of lime.
