In 1994, Saskatchewan Highways and Transportation (SHT) became involved in evaluating subgrade performance (the Subgrade Study). The Canadian Strategic Highway Research Program (C-SHRP) which operates within the Transportation Association of Canada (TAC) was also promoting their newly developed Bayesian Software by sponsoring Joint C-SHRP/Agency Applications whereby technical assistance was provided to the provincial highway agencies towards the development of Bayesian performance models. Saskatchewan's Bayesian project, Subgrade Shear Failure, was accepted by C-SHRP and would incorporate data collected in the Subgrade Study. The objective of the Bayes project was to learn the Bayesian learn the Bayesian methodology and to develop a mode, incorporating field data and expert judgement. Field data was collected from two gravel haul roads in 1994 and the Expert data was obtained from department and external experts in the spring of 1995. (A)
