EVALUATION OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT

THE PURPOSE IS TO EVALUATE THE PERFORMANCE OF A CONTINUOUSLY REINFORCED CONCRETE PAVEMENT (CRCP) UNDER THE INFLUENCE OF CONCRETE SHRINKAGE, TEMPERATURE CHANGE, AND TRAFFIC AT FAIRBAULT, MINNESOTA. THE THEORY OF CONTINUOUSLY REINFORCED PAVEMENT IS DISCUSSED. THE PROJECT DESIGN AND LAYOUT, CONSTRUCTION PROCEDURES AND MATERIALS ARE DESCRIBED. CRACK SURVEY RESULTS, LONGITUDINAL PAVEMENT AND MOMENTS, ROUGHOMETER MEASUREMENTS, PAVEMENT FAILURES AND COST ANALYSIS ARE ALSO PRESENTED AND DESCRIBED. BASED ON THE FINDINGS OF THIS INVESTIGATION, IT IS RECOMMENDED THAT AT LEAST 0.7 PERCENT DEFORMED STEEL REINFORCEMENT BE USED ON ALL CRCP BUILT IN MINNESOTA, AND THAT LARGE EXPANSION JOINTS BE USED IN PLACE OF END ANCHORS TO ACCOUNT FOR THE LONGITUDIANL END MOVEMENTS. IT IS SUGGESTED THAT PERFORMANCE SURVEYS BE MADE OF THE CRCP BUILT SINCE 1966 TO DETERMINE IF SUCH PAVEMENTS WILL GIVE ACCEPTABLE SERVICEABILITY IN MINNESOTA.
