摘要

Geotechnical evaluation of sub-grade soil material invariably forms as one of most important steps in designing of road pavements. Sub-grade soil, whether in filling or in cutting, is required to be evaluated for critical design parameters in the form of CBR, as per IRC-37 and MORTH. CBR is an pragmatic test which is used in design of new flexible pavements and rehabilitation of existing pavements all over the world. The conventional CBR test procedure is time consuming, relatively expensive and has generally low repeatability and/or reproducibility. This repeatability and/or reproducibility has been found critically very low for sensitive Lacustrine soils, which are locally referred as Kerawa Soils in Kashmir Valley. In order to find a solution to above problems, Dynamic Cone Penetrometer (DCP) was used in this study. The Dynamic Cone Penetrometer test (DCPT) is widely used to assess in-situ strength of undisturbed soil and compacted sub-grade materials. As such efforts in this study have been aimed at developing a reliable correlation of DCPT values and CBR for Lacustrine/sedimentary upland soil formations which can be used to facilitate quick evaluation of road sub-grades, in-place.
