Stabilisasi Tanah Lempung dengan Campuran Pasir Pantai Terhadap Nilai CBR (Penelitian)

Abstract

The development of human developing era have undergone very significant progress since a thousand years past, including the transportation sector as well. Human activities in fulfilling the needs of his life sometimes has to lead to mobilize, therefore needed a means of supporting the mobilization activities. As you well know, the ground is a supporter of road construction materials composed of three ingredients, namely grain, water and air (Craig.F.R, Susilo Budi S “Mekanika Tanah Edisi 4, 1987) so that required a mathematical calculation in figuring the value of power support. The third order of the material is very influencing power support on the ground, so that the need to make the determination of the parameters for the sake of analysis. The purpose of this research is to analyze the value of the California Bearing Ratio (CBR) ground clay with addition of sand (quarsa) as an ingredient mix, unable to amplifies power support land on a layer of soil roughness. The purpose of this research is to find out how big the influence of addition of sand in soil clays of the California Bearing Ratio (CBR). As for the research conducted is done in 3 variations of 0%, 15%, 30%. As for the results of this research are as follows: 6.803; 10.339; 14,409%. From the results of the value of the California Bearing Ratio can be seen that the addition of sand quarsa on soil clays showed an increase in the value of the California Bearing Ratio in soil clays.
