Determination of CBR of Subgrade Soil at field density (Un soaked) and Saturate density (Soaked) condition from DCP Test
Keywords:
CBR, FMC, FDD, DCPAbstract
Laboratory CBR test in Un soaked and Soaked condition is time consuming, expensive and indirect representation of filed condition, so there is a need of performing direct monitoring of strength at site for subgrade soil to design flexible Pavement and also for verification of quality of subgrade during construction and also under operation period which demands fast & easy way to verify subgrade strength parameters The present study reflects on experimental investigation on various soils at F.D.D. and FMC by correlating DCP with CBR test results in Un soaked as well as soaked condition at Field density that will helpful to the highway engineer in estimate Un soaked and Soaked CBR value at Field Density from DCP results obtained from site. Hence time will be saved and site condition assessed properly.
