Performance-Based Evaluation of Expanded Polystyrene (EPS) Thickness in Integral Abutment Bridges

The objective of this study is to establish performance-based framework for calculating the required thickness of Expanded Polystyrene (EPS) elastic inclusion at integral bridge abutments. The results will be implemented in Chapter 17 of the Virginia Department of Transportation's (VDOT's) Manual of the Structure and Bridge Division. Reductions in integral bridge construction and maintenance costs are expected to be derived from this study.
