Abstract

Clay soil is a cohesive soil with low bearing capacity and low shear strength where the load on it will be limited. The addition of water content in clay soil will result in changes in soil volume that will affect the strength of the soil. The research aims to know how much water content affects the values of consolidation settlement. A consolidation test was carried out three times with variations of the original soil sample, 35% water content and 30% water content. The results obtained a settlement of 0,1864 cm for original water content, 0,1677 cm for 35% water content, and 0,1414 cm for 30% water content.

Abstract

Soil compaction is required so that the embankment is strong and balanced with structural and non-structural loads. One of the efforts to handle soil with low bearing capacity is to change the subgrade using soil that is considered good. Therefore, an attempt was made to estimate the density of the soil in the field by conducting a sand cone test on the selected embankment material on the Yos Sudarso road work, Palangka Raya City. The sample used in this study came from Hampangen Village, Kasongan Baru Village, Katingan Hilir District, Katingan Regency, Central Kalimantan Province. The results of tests carried out on laboratory density testing and sand cone testing on Yos Sudarso Street, Palangka Raya City can be ascertained that the density obtained from dry soil density γdry = 1.29 g/cm3, maximum dry density γd lab = 1.35 g/cm3 γdr / γd lab x100 = Dr. So the approved density is Dr = 95.86%.
