ILLINOIS DEPARTMENT TO TEST NEW BRIDGE BUILDING TECHNIQUES

NEW TECHNIQUES IN BRIDGE CONSTRUCTION WILL BE TESTED IN SIDE-BY SIDE COMPARISONS WITH CONVENTIONAL METHODS IN TWO RESEARCH PROJECTS PROPOSED BY THE ILLINOIS DIVISION OF HIGHWAYS. THE PROPOSAL CALLS FOR CONSTRUCTION OF BRIDGE STRUCTURES AT TWO DIFFERENT SITES. A FOUR-SPAN, DUAL- STRUCTURE CONCRETE BRIDGE WITH GALVANIZED REINFORCEMENT IN THE CONCRETE DECKING IS PROPOSED FOR ONE THE PROJECTS WHICH WILL TEST THE EFFECTIVENESS OF GALVANIZED REINFORCING STEEL AS A DETERRENT TO SPALLING IN CONCRETE BRIDGE DECKS. IN THE DUAL STRUCTURES, ONLY THE TOP REINFORCING STEEL WILL BE GALGANIZED; IN THE OTHER, BOTH TOP AND BOTTOM STEEL WILL BE GALVANIZED. THE OTHER PROJECT WILL COMPARE MAINTENANCE COSTS FOR GALVANIZED AND UNGALVANIZED STEEL IN A STRUCTURAL STEEL BRIDGE. IT ALSO WILL BE A DUAL STRUCTURE BRIDGE, WITH STEEL IN ONE STRUCTURE TO BE GALVANIZED. THE COMPANION STRUCTURE BUILT ALONGSIDE WILL RECEIVE THE STATE'S STANDARD SYSTEM. /AUTHOR/
