MTI/MoDOT Transportation Geotechnics Research Program - Task 1

This project is one component of a comprehensive research program to develop new and improved load and resistance factor design (LRFD) specifications, and associated commentary documents, for design of bridge foundations and earth slopes. This specific portion of the work focuses on completing an extensive lab and field testing program to quantify variability and bias in relevant design parameters (e.g. shear strength and consolidation parameters) as a function of specific boring, sampling, and testing techniques. Results of this work will also lead to recommendations for improved site characterization procedures for Missouri Department of Transportation (MoDOT). Recommended procedures for establishing appropriate values of variability and/or bias in design parameters based on site specific testing will also be developed. Results from this task are crucial to development of improved, MoDOT specific load and resistance factors and to the broader objective of developing design techniques that will reduce costs while maintaining appropriate risk for bridges and earth slopes.
