Abstract

Sub grade is base soil as foundation which supports traffic load on pavement road. Hence pavement road design is obtained by condition of sub grade. The problem which occurred is sub grade has low bearing capacity (low California Bearing Ratio/CBR) and high swell-shrinkage that causing soil local collapse in the rain season. The principal methods for solving the above problems is : 1) refinement or stabilization of sub grade and 2) minimizing water influence by keep the water infiltrate into soil or build well drainage. This paper contains economic and engineering aspects from soil-cement and geotextile reinforcement as refinement sub grade solution on road section at Smewah Sukaraja, which is road to oil exploration at Sukaraja Laboratories test indicates that sub grade soil of Smewah-Sukaraja road section has fluid limit value is 25,53% , plasticity index 15,98, CBR 0,1” 3,31% and CBR 0,2’’ = 2,65%, so it is inadequate as road sub grade. Time for soil cement refinement method and geotextile reinforcement is 120 days and 90 days. Cost of each method is Rap. 5.270.500.000, 00, and Rp. 5.223.000.000, 00 Keywords: sub grade, soil-cement, and geotextile.
