INTERIM REPORT-LABORATORY INVESTIGATION OF THE HORIZONTAL SHEAR STRENGTH OF GROUT KEYS AND TONGUE OF FORK CONNECTORS

THIS INTERIM REPORT DESCRIBES A LABORATORY INVESTIGATION OF THE HORIZONTAL SHEAR STRENGTH OF GROUT KEYS AND TONGUE AND FORK CONNECTORS PROPOSED FOR USE IN A COMPOSITE PAVEMENT CONSISTING OF PRECAST AND PRESTRESSED CONCRETE PANELS POST- TENSIONED IN PLACE AND COVERED WITH ASPHALTIC CONCRETE. THE REPORT DESCRIBES THE LABORATORY TESTING OF PROTOTYPE KEYS AND CONNECTIONS WITH SIMULATED HORIZONTAL SHEARING FORCES, PRESENTS TEST DATA, AN EVALUATION OF THE DATA, AND A DISCUSSION OF THE EVALUATION WITH RESPECT TO THE APPLICABILITY OF THE TEST RESULTS TO THE OVERALL STUDY ON THE CONCEPT OF THIS TYPE OF COMPOSITE PAVEMENT. THE AUTHOR CONCLUDES ON THE BASIS OF THIS INVESTIGATION' THAT 100 PERCENT OF THE PANEL PRESTRESS CAN BE TRANSMITTED THROUGH THE GROUT KEYS AND CONNECTORS TO ADJACENT PANELS' THAT THE STRENGTH OF THE CONNECTORS BECAME CRITICAL WITH 0.3 OF AN INCH OF PANEL DISPLACEMENT AND PANEL STRESS OF 125 P.S.I.; AND, THAT HORIZONTAL PANEL DISPLACEMENT RESISTED BY FRICTION AND THE CONNECTORS AMOUNTED TO AN INCREASE IN PANEL STRESS OF 1.52 P.S.I. PER 0.001 INCH OF DISPLACEMENT. /BPR/
