Evaluation of Pile Load Tests for Use in Missouri LRFD Guidelines

The current Missouri Department of Transportation (MoDOT) Engineering Policy Guide (EPG) 751.36 for Driven Piles includes resistance factors to be used in the Load and Resistance Factor Design (LRFD). These resistance factors were adopted from the current AASHTO LRFD Bridge Manual (2010). These resistance factors at the national level tend to be in the conservative side and closely tied to the level of effort and engineering conducted during the installation of the foundation elements (static pile load and dynamic method tests). A series of load tests (3) will be conducted at three construction bridge sites along the Missouri highway system. The results will be used to adjust the resistance factors that have been developed previously based on high strain dynamic methods only.
