Pengaruh Penambahan Kapur Batu Pada Tanah Merah Terhadap Nilai California Bearing Ratio

Abstract

The development of human civilization has experienced significant progress since the last thousand years, including the transportation sector. Human activities in fulfilling their daily needs must sometimes lead to mobilization, because of that the facilities needed to support these mobilization activities are needed. As has been known together, land is a supporting material for road construction which is composed of three materials, namely granules, water and air (Craig.FR, Susilo Budi S "Soil Mechanics Edition 4, 1987) so that a mathematical calculation is needed in finding the value of power support it. The arrangement of the three materials greatly affects the carrying capacity of the soil, so it is necessary to determine parameters for the sake of analysis. The purpose of this research is to analyze the value of California Bearing Ratio (CBR) of red soil with the addition of stone lime as a mixture material, able to strengthen the carrying capacity of the soil in the soil pavement layer. The purpose of this study was to determine how much influence the addition of stone lime on clay to the value of California Bearing Ratio (CBR). The research conducted is carried out in 3 variations of 0%, 15%, 30%. The results of this study are as follows: 6,1%; 64%; 83,5%. From the results of the California Bearing Ratio, it can be seen that the addition of stone lime to clay shows an increase in the value of California Bearing Ratio on red soils.
