PROGRESS REPORT ON SPECIAL INVESTIGATION ON THE ECONOMIC VALUE OF STEEL REINFORCEMENT IN CONCRETE ROAD SURFACES

IN THE EARLY FALL OF 1924, THE HIGHWAY RESEARCH BOARD WAS REQUESTED TO CONDUCT A NATION-WIDE FACT-FINDING SURVEY ON THE ECONOMIC VALUE OF REINFORCEMENT IN CONCRETE ROADS. THIS REQUEST WAS URGED NOT ONLY BY ENGINEERS, BUT ALSO BY CERTAIN INTERESTED AGENCIES WHO FELT THAT SUCH AN INVESTIGATION WAS NECESSARY TO DETERMINE THE TREND OF FUTURE MANUFACTURING CONDITIONS. UNDER THE POLICIES OF THE NATIONAL RESEARCH COUNCIL, INDUSTRIES ARE ENCOURAGED TO CONTRIBUTE TO THE COST OF INVESTIGATIONS OF THIS KIND, AND THIS PLAN IS BEING FOLLOWED IN THIS SURVEY. IN THIS STUDY AN EFFORT IS BEING MADE TO DETERMINE FROM A SURVEY OF EXISTING ROADS, THE INFLUENCE OF STEEL REINFORCEMENT ON THE RESISTANCE OF THE SLAB TO TRAFFIC; OF SUBGRADE; OF CLIMATIC CONDITIONS; OF THE CONDITIONS UNDER WHICH STEEL REINFORCEMENT IS ESPECIALLY BENEFICIAL TO CONCRETE SLABS; OF THE EFFECT OF SLAB DESIGN ON THE EFFICIENCY OF REINFORCEMENT; AND FINALLY, OF THE RELATIVE COST OF PLAIN AND REINFORCED CONCRETE ROADS, CONSIDERING THE INITIAL INVESTMENT TOGETHER WITH THE ANNUAL MAINTENANCE AND RENEWAL CHARGE. FINAL CONCLUSIONS WILL BE BASED ON RESULTS OF HIGHWAY EXPERIMENTS, REPORTS OF PREVIOUS ROAD SURVEYS AND MAINTENANCE AND CONSTRUCTION COSTS CORRELATED WITH THE PRESENT CONDITION OF ROAD SURFACES THAT HAVE BEEN IN SERVICE FROM ONE TO TWELVE YEARS. THE SURVEY IS MAINLY CONFINED TO SURFACES CONTAINING CONSIDERABLE LENGTHS OF BOTH PLAIN AND REINFORCED SECTIONS OF THE SAME AGE, DESIGN AND TRAFFIC CONDITIONS. SURFACES CONFORMING TO THESE REQUIREMENTS HAVE BEEN LOCATED IN ABOUT THIRTY STATES, RANGING FROM CONNECTICUT TO CALIFORNIA, AND MINNESOTA TO TEXAS. UPON COMPLETION OF THE SURVEY A COMPREHENSIVE REPORT OF THE FINDINGS WILL BE ISSUED.
