Analisa Perhitungan Daya Dukung Tanah pada Lapisan Subgrade Jalan Menggunakan Metode California Bearing Ratio Lapangan

Abstract

Roads are a means of technology that is helping the lives of everyday people. Human activities in meeting their needs can not be separated from the process of mobilization, so that human life can not be separated from the road. The modern road construction, made up of various layers, namely a layer of subgrade, base layer, coating floors and pavement work. Therefore, the construction of the road now are laminated, the strengths of each layer of road works need to know the parameters of strength. The parameters are soil classification, soil moisture content, soil density and soil bearing capacity. The purpose of the research done in this paper is to analyze the carrying capacity of the land base in highway construction projects Kualanamu International Airport -Tebing Tinggi, and the purpose of writing this paper was to determine the carrying capacity of the foundation soil by using California Bearing Ratio field. In accordance with the objectives of this thesis, then the value of California Bearing Ratio test on a three-point test, namely: STA 46 + 150, STA 0 + 212.5, and STA 44 + 625-44 + 825 (R / L). The results of testing this California Bearing Ratio row is 12:54%, 13:02% and 12.84%. The values obtained California Bearing Ratio has met the standard value for a road that is 6%. From all the data obtained in experiments conducted in this thesis a carrying capacity of land by 6910. Values of soil bearing capacity is the one who will be the reference carry out further work.
