Stabilisasi Tanah Lempung Menggunakan Pasir Pantai Terhadap Nilai CBR Unsoaked

The problem of strength and resilience of soil is one of things that really need to considered in the planning and construction work of a civilian building . This is because the land in question serves as a medium that holds the load or the action of a construction that is built on it. The construction of soil on Kp. Juhut Street – Karang Tanjung Pandeglang Regency has a low carrying capacity by having a California Bearing Ratio of 3,1% by testing the Dynamic Cone Penetration, so that the value of California Bearing Ratio on the road is below the standard of 5%, then the land stabilization needs to be done. Stabilization using beach sand material is one way to meet the needs of the required strength. This study attempts to knowledge of and classification of land in the Kampung Juhut, Kecamatan Karang Tanjung, Kabupaten .Pandeglang with the Unified Soil Classification System (USCS). And to knows the CBR unsoaked by the addition of beach sand of the percentage 0%, 12%, 24%, and 36% for ripening with 0, 7, 14 days . The results of studies show that based on some classification systems USCS, the soil types including in the classification OH, that is clay with organic plasticity. Results Based on the addition of beach sand by 36% and curing for 14 days, the highest CBR value was 28% and was included in the good category for base or subbase.
