Federal Highway AdministrationUS Transportation CollectionVarious sites that were penetrated by Louisiana's Department of Transportation and Development (DOTD) foundatioon boring crews with the mechanical cone penetrometer (Dutch Cone Penetrometer) and rotary drill rig (core borings) are discussed. A comparison of the resultant tests is given including stratigraphy determination, soil consistency, and ultimate capacity. Also some of the results of a corollary study of an electronic cone penetrometer (ECP) (Fugro Cone) performed in the same area are shown and compared.Results of this study show that the mechanical cone penetration (MCP) test compares favorably (better than conventional lab test) with test piles driven in the vicinity, provided the foundation material is not too soft. Correlation between MCP and ECP is also given. In addition, these results correlate well with known geology
