Load factor design (LFD) codes have been used in the US since the 1970’s, and in the highway industry since 1977, but their application was limited to the design of superstructure components. Introduction of the AASHTO LRFD Bridge Design Specifications (LRFD Specifications, 2002) in 1994 represents the first instance in the US where load and resistance factor design (LRFD) was codified for the geotechnical design of highway substructure features. While a few state departments of transportation (DOTs) proactively pursued implementation of the LRFD Specifications, the process has been slow. This implementation has been slowed, in part, by resistance to change, lack of applicable software, and inadequate staff training. More importantly, a number of problems have arisen that can be attributed to changes in the LRFD Specifications that resulted in noticeable differences with past design practice. This paper highlights the challenges that have been encountered and the measures aken to correct and implement the LRFD Specifications to gain the confidence of highway owners and designers.
