Stabilisasi Tanah Lempung Dengan Menggunakan Pasir Pantai Monpera Balikpapan Dan Pengaruhnya Terhadap Nilai Daya Dukung Tanah (Studi Kasus Pada Km 8 Arah Stt Migas Menuju Tembusan Pantai Manggar)

Abstract

In this study using clay to be stabilized and comes from KM 8 Directions STT Migas to the Manggar Beach translucent, related to the mixed material used, namely Monpera Beach sand with a mixed variation of 10%, 20 %, 30%, 40%, and 50%. Based on the sieve analysis test and the classification of the AASHTO method, namely, the soil that passed the No. sieve. 200 obtained a percentage of 39,175%. In the atterberg test, the original soil limit for the liquid limit (LL) was 62.1% and the plasticity index (PI) was 17,0%. The results of the AASHTO classification and the types of soil grouping according to Hardiyatmo are classified as loamy soils and medium plasticity. In the soil compaction test, the optimum water content was 1,54 gr/cm3 and the optimum water content was 16,67%. The original soil CBR obtained a CBR value of 10,41%. As for the CBR test of mixed beach sand soil 10%, 20%, 30%, 40%, and 50% respectively, namely 10,84%, 12,84%, 10,76%, 13,44%, and 15, 09%. It was concluded that the more beach sand, the more the carrying capacity of the soil will increase, so that the soil becomes stronger to withstand the load on it.
