ANALYSIS OF CBR VALUE ON PEAT OF OGAN KOMERING ILIR

Abstract

Peat soil has unique charateristics when viewed from the perpective of its CBR value. This is because the soil contains soil-forming materials, in addition to its high acidity and water content, so that it will affect the bearing capacity of the soil and the value of the California Bearing Ratio (CBR). Research on CBR values in Ogan Komering Ilir Regency was carried out in Tulung Selapan Ilir Village, Tulung Selapan District, and Sumber Hidup Village, East Pedamaran District. The value of the California Bearing Ratio (CBR) of peat soil in Tulung Selapan Ilir Village is 2.83%. Meanwhile, the CBR value of the peat soil in Sumber Hidup Village is 2.82%. According to Bowles, the CBR values of the two locations are categorized as “very poor”. Meanwhile, based on Bina Marga, including road subgrade, the category is bad.
