Expansive soils also called swelling soils are known for volume changes due to seasonal moisture changes. Swelling soils in nature may have different liquid limit (LL) and percent coarse fraction (CF). The volume change characteristics of expansive soils are influenced by both CF and LL of fine fraction. In this study an attempt has been made to study the influence of CF on compaction, strength and...
Numerous studies demonstrated the possibility of utilizing fly ash in the construction of embankments, road subgrades and stabilization of a wide range of soils. The present investigation aims at determining the optimum fly ash (OFA) for mechanical stabilization of expansive soils. Four different soils were tested for compaction characteristics and unconfined compressive strength with and without...
