PENGARUH STABILISASI TANAH LEMPUNG DENGAN MENGGUNAKAN BAHAN CAMPURAN PASIR KUARSA TERHADAP UJI KOMPAKSI

Abstract

The Land is a material that has the function to support a structure that is above it. In this study the type of soil studied was clay. Characteristics of clay soils are easy to crack when in dry conditions but very soft if in wet conditions, have high water content, and have a low carrying capacity. With a low carrying capacity can affect the quality of the soil or soil structure on the road, so it is necessary to do soil stabilization to improve the soil structure. Stabilization is used using a mixture of quartz sand which is considered relatively cheap and easy to obtain. The purpose of this study is to determine the effect of quartz sand on compacting tests.Clay soil used is clay in the area of ​​Bojong Kalong Village, Nyalindung District, Sukabumi Regency with a mixture of quartz sand content at a percentage of 0%, 30%, 40%, and 50%. Tests carried out are compacting tests that produce optimum moisture content and maximum dry weight content.The results of this study in the compacting test with the addition of quartz sand can reduce the value of water content by 23.90% and increase the weight value of dry contents in the soil by 1,177 gr / cm3. So that the most influential addition to clay is at a percentage of 50%.
