FINAL REPORT: PERFORMANCE OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT - 184 - SOUTHINGTON
CONNECTICUT'S CRCP WAS BUILT AS AN EXPERIMENTAL PROJECT IN 1962. THE SIX-LANE DIVIDED HIGHWAY (I84) WAS BUILT LANE-AT-A-TIME BY THE DOUBLE STRIKE-OFF METHOD. PLAIN WIRE FABRIC AND HIGH STRENGTH RE-BAR MATS WERE USED TO PROVIDE 0.6% REINFORCEMENT. DIFFICULTIES EXPERIENCED DURING PAVING ARE DESCRIBED. THE SECTIONS CONTAINING THE RE-BAR MATS ARE PERFORMING WELL, BUT THE FABRIC AREAS HAVE 12 WIDE CRACKS WHERE THE STEEL HAS PARTED. THE CRACKS APPEAR TO HAVE PROGRESSIVELY OCCURRED DURING EXTENDED COLD PERIODS. THE CONVENTIONAL PAVEMENT HAS EXPANDED AND CLOSED THE TERMINAL JOINTS, AND SUBSEQUENTLY TWO-FOOT WIDE RELIEF JOINTS WERE CUT INTO THE PAVEMENT. INFORMATION IS PRESENTED ON MOVEMENTS, WEATHER, CRACK OPENINGS. LOGICAL EXPLANATIONS ARE PRESENTED FOR EXPLAINING THE BEHAVIOR AND RECOMMENDATIONS ARE SUGGESTED. FOUR PREVIOUS UNCIRCULATED INFORMAL REPORTS HAVE BEEN MADE. THIS IS THE FIRST FOR WIDESPREAD DISSEMINATION. /BPR/
