This synthesis reviews the cone penetration testing (CPT) current practices of departments of transportation (DOTs) in the United States and Canada. Information is presented on cone penetrometer equipment options; field testing procedures; CPT data presentation and geostratigraphic profiling; CPT evaluation of soil engineering parameters and properties; CPT for deep foundations, pilings, shallow foundations, and embankments; and CPT use in ground modifications and difficult ground conditions. The report is designed to serve as a resource to states and provinces interested in taking advantage of CPT technology by identifying applications, design procedures, advantages, and limitations for successful implementation. Information was gathered by a literature review of domestic and international experience, a survey of DOTs in the United States and Canada, and interviews with practitioners.
