    Abstract

    ABSTRACT Dwi Rizki Prasetia, 2016. Peat Soil Stabilization Using Mixture of Synthetic Gypsum (CaSO4. 2H2O) and Salt (NaCl) Based on CBR test. Thesis, Civil Engineering Department, Faculty of Engineering, Sebelas Maret University. Peat soil is categorized weak soil layer, which is soil with bad condition and problematic if it will be built a highway pavement construction thereon. Need to efforts to increase the carrying capacity of the peat, one of which is a soil stabilization chemically, by adding additives which can react with the soil. In this study, the added material used is synthetic gypsum (CaSO4. 2H2O) and salt (NaCl). The reactions that occur here observed and analyzed in the laboratory CBR parameter value changes of soaked condition and unsoaked condition. This research was conducted in the laboratory of soil mechanics Sebelas Maret University of Surakarta. The addition of synthetic gypsum percentage of 10%, 15%, 20% and salt of 2%, 4%, 6%. Variations mixture created four variants those are original peat soil, peat plus synthetic gypsum, peat plus salt and peat plus synthetic gypsum plus salt. The results showed that the CBR value of the largest are in the mix, peat + 20% + 6% NaCl gypsum is 5.08 in soaked condition and 5.21 in unsoaked condition. Key Words : Peat Soil, Stabilization, Synthetic Gypsum, Salt, CBR Test
