TRC1905 - Implementing CPT Procedures in ARDOT Geotechnical Designs

The overarching objective of this research effort is to examine the applicability of using cone penetration test (CPT) to reduce uncertainties associated with geotechnical subsurface investigations. The main goal of this project is to review and implement comprehensive CPT-based geotechnical design procedures for site exploration, interpretation of soil behavior, and design of shallow/deep foundations and embankments in Arkansas. Work Plan will include conducting a literature search, collecting field testing procedures, conducting the field tests (six sites), analyzing resulting CPT data, and applying results to specific geotechnical design. Tasks will be performed by Research Section personnel with the help of Materials Division. The research project is broken into two phases. Phase 1 will mostly cover Year 1 of the project and will introduce CPT rig and its in-field operations to ARDOT personnel involved with this study. Phase 2 will cover Year 2 of the project and will deal with developing best practice for CPT field testing and CPT Geotechnical designs.
