REVIBRATION OF RETARDED CONCRETE FOR CONTINUOUS BRIDGE DECKS

MAINTENANCE PROBLEMS CREATED BY SPALLING OF REINFORCED CONCRETE BRIDGE DECKS ARE DISCUSSED. REVIBRATION STUDIES OF RETARDED CONCRETE ARE SHOWN TO BE USEFUL IN ELIMINATING SURFACE AND INTERIOR CRACKS IN PLASTIC CONCRETE BY PRODUCING A MORE HOMOGENEOUS AND CRACK-FREE BRIDGE DECK IN ITS HARDENED CONDITION. SURFACE REVIBRATION IS ALSO AN EFFECTIVE AND ECONOMICALLY FEASIBLE METHOD TO CLOSE SURFACE CRACKS, INTERNAL CRACKS OR PLANE-OF-WEAKNESS CRACKS IN PLASTIC CONCRETE IF THE PENETRATION RESISTANCE IS NOT IN EXCESS OF 60 PSI. THE SURVEY CONCLUDES THAT THE TECHNIQUE OF REVIBRATION PRODUCES NO HARMFUL EFFECTS IN THE SHORT TERM, AND OFFERS PROMISE OF PRODUCING MORE DURABLE CONCRETE OVER THE LONG TERM.
