SUMMARY OF EXPERIMENTAL BRIDGE FEATURES. FINAL REPORT

Experimental bridge features and service problems investigated during this study are reviewed. Those were epoxy-coated reinforcing steel, stay-in-place forms, experimental deck features (rotary compaction and broomed deck finishing), precast segmental bridges, steel-corrosion control methods (weathering steel and hot-dipped galvanizing), microsilica concrete, failures of masonry coatings, and failures of aluminum guardrail-retaining nuts. Several features including latex and low-slump overlays, epoxy-coated reinforcing steel, and broomed deck finishes (for state-built bridges), are now in common use. Most of the other experimental bridge features were performing satisfactorily. A corrosion problem was observed on one weathering steel bridge. Analyses of failures of masonry coatings and the aluminum nuts resulted in identification of the probable causes of the failures and remedial recommendations. The report also contains recommendations for further research.
