The study proposed in this research will first work with Mn/DOT and other regional DOTs to build upon their experiences in implementation of cone penetration testing for transportation projects, and then address additional issues specific to the needs of the Wisconsin Department of Transportation. Data will be collected in Wisconsin and discussed in light of conventional geotechnical soil properties so that practitioners are familiar with factors controlling the behavior of CPT measurements, minimizing the reliance on blind application of ‘black box’ data processing and interpretation programs.


The work plan and experimental design are developed around aiding engineers and geologists in within the Wisconsin Department of Transportation to understand the mechanisms controlling cone penetration test readings so that they can decide when the testing method is appropriate for use, know how to design an appropriate exploration program, and rapidly interpret the results of the tests for more efficient and reliable engineering.


  1. Literature search.
  2. Obtain and analyze Wisconsin CPT data.
  3. CPT investigations adjacent to past and current WisDOT borings.
  4. Analysis of data and summary report.
