A total of 61 cone penetration tests were performed at 14 sites in the state of Wisconsin. Data reinforced conclusions from practice in Minnesota and previously performed test programs related to the Marquette Interchange and Mitchell interchange project that use of the CPT can be successful in glacial geologies. Within in this study CPTs were performed to depths in excess of 75 feet in alluvial deposits, outwash, and lacustrine soils. Difficulties were encountered in clay tills and fill placed for highway structures. However, previous experience in Milwaukee by commercial CPT operators had success in clayey tills of eastern Wisconsin.
