Integral Abutment Connection Details for Accelerated Bridge Construction
The Iowa Department of Transportation has released a report that investigates using mechanical couplers to splice the foundation elements to the superstructure elements of bridges while applying accelerated bridge construction (ABC) techniques. Specifically, this report determines the effect of ABC methods on the integral abutment, which can eliminate the need for expansion joints between the substructure and superstructure of bridges.
