Synthesis of Information Related to Highway Problems. Topic 37-14. Cone Penetration Test: State of the Practices

The Cone Penetration Test (CPT) is being used for site investigations to determine soil stratigraphy and in-situ soil properties. It is also being used to predict load capacity of pile foundations, liquefaction due to seismic events, and consolidation potential of earthworks. There are a wide range of methodologies available in the literature for interpreting CPT data. CPT applied to transportation projects has the potential to save time and money while providing better and more detailed site characterization. While some transportation agencies have extensive experience with this technology, most agencies are just beginning to investigate the potential benefits of the cone penetration test. A synthesis will be developed covering the experiences of transportation agencies, private consulting firms, and construction industries, both foreign and domestic, in the application of design methodologies utilizing the CPT technologies. The synthesis will identify current practices, design methodologies, and software that are being used effectively in foundation design of bridges and other structures. It will serve as a resource to states that are interested in taking advantage of the technology by identifying applications, design procedures, cost-benefits, and limitations for successful implementation.
