END ANCHORS FOR CONTINUOUSLY-REINFORCED CONCRETE PAVEMENTS
UNRESTRAINED END SECTIONS OF CONTINUOUSLY-REINFORCED CONCRETE PAVEMENTS HAVE BEEN OBSERVED TO MOVE SEVERAL INCHES LONGITUDINALLY DUE TO THERMAL, SHRINKAGE, OR SWELLING STRAINS. DURING THE LAST FEW YEARS A NUMBER OF CONTINUOUS SLABS HAVE BEEN PROVIDED WITH SUBGRADE ANCHORS OF VARIOUS CONFIGURATIONS TO PREVENT THESE LARGE END MOVEMENTS. THIS PAPER REPORTS AN EXPERIMENTAL AND THEORETICAL STUDY TO DEVELOP GUIDELINES FOR SELECTING AND DESIGNING A SUITABLE END ANCHOR SYSTEM. A FULL-SCALE EXPERIMENTAL INVESTIGATION OF TWO DIFFERENT END ANCHOR CONFIGURATIONS-A CYLINDRICAL PILE-SHAPED ANCHOR AND A RECTANGULAR SOIL-SHAPED ANCHOR-WAS CONDUCTED. FOUR TEST ANCHOR UNITS WERE SUBJECTED TO A HORIZONTAL THRUST APPLIED BY A JACKINGFRAME AT THE PAVEMENT SLAB LEVEL. TWO OF THE TEST UNITS WERE RIGIDLY ATTACHED TO A 15-FT LENGTH OF 10-IN THICK SLAB TO SIMULATE THE INTERACTING ANCHOR-PAVEMENT SYSTEM. THE OTHER TWO TEST ANCHOR UNITS WERE WITHOUT ATTACHED SLAB. LOADS, DEFLECTIONS, AND ROTATIONS WERE MEASURED. A THEORETICAL ANALYSIS HAS BEEN DEVELOPED FOR THE ELASTIC AND PLASTIC RANGE OF END ANCHOR RESPONSE. THE MORE COMPLEX THEORETICAL SOLUTIONS HAVE BEEN PRESENTED IN THE FORM OF CURVES FOR USE IN DESIGN. /AUTHOR/
