Abstract

This study evaluates the physical and mechanical properties of expansive clay soil (Bobonaro clay) from Naitimu Village, Tasifeto Barat District, Belu Regency, East Nusa Tenggara, Indonesia. Laboratory tests including Atterberg limits, grain size analysis (sieve and hydrometer), specific gravity, compaction, CBR, and swelling potential reveal the soil classifies as low-plasticity inorganic clay (CL per USCS) with moderate activity (Ac=1.09), liquid limit 41.75%, plasticity index 20.14%, natural moisture 5.42%, and specific gravity 2.45. These properties indicate medium swelling risk, requiring stabilization like mechanical compaction or additives for safe use in road bases and building foundations to mitigate shrink-swell damage.
