Adhesive Anchors for Retrofit/Repair of Bridge Rails: Summary Report

摘要

This project focused on determining the magnitude and location of force to the rail anchorage reinforcement for two current TxDOT bridge rail systems, the T501 and the T203 concrete bridge rails under severe loading conditions. These rails were studied so that an acceptable structural repair using adhesive anchors could be made to rails damaged due to impacts. The project explored the ultimate strengths of the T501 and T203 bridge rails and the transfer of these forces to the rail anchorage systems for both the T501 and T203 bridge rails with the intent to develop suitable repair and/or retrofit designs.
