BRIDGE (H000)Patching Bridge Decks (H520)FOG-808FUNCTIONFE01: DistrictFE02: Central OfficeFD04: Six-Year PlanCB01: Rural Secondary "Emergency"CB06: Rural Secondary "Regular"RECOMMENDEDPROCEDURE1. Discuss with crew the requirements of the job, including themanufacturer’s recommendations for curing material.2. Place traffic-control devices and station flaggers as necessary.3. Sound bridge deck, and delineate the areas of deterioration.4. Saw the perimeter of deteriorated area with a concrete saw to aminimum depth of ¾ inch if not encountering steel.5. Use pavement breakers to remove deteriorated concrete within thesawed area. Use more breakers at any time the breaking operationbecomes the production control factor.6. If a reinforcement bar is exposed, remove ¾-inch concrete under thebar.7. Sweep and remove all trimmings.8. Blast-clean all steel exposed to white metal and clean concrete.9. Mix quick-setting concrete material in accordance withmanufacturer’s recommendations.10. Paint the hole and the steel with a grout, if recommended.11. Place mixed material in prepared hole.12.
