LOAD TRANSFER CHARACTERISTICS OF A DOWELLED JOINT SUBJECTED TO AIRCRAFT WHEEL LOADS, WITH DISCUSSION

INTERIM RESULTS OF A STUDY BEING CONDUCTED ON THE LOAD TRANSFER CHARACTERISTICS OF DOWELS USED IN AIRFIELD PAVEMENT EXPANSION JOINTS ARE PRESENTED. THE SLAB CONSISTS OF TWO 10-IN THICK, 15-FT WIDE, AND 25-FT LONG SECTIONS JOINED BY A 3/4-IN EXPANSION JOINT ACROSS WHICH 1 1/8-IN DIAMETER DOWELS ARE PLACED ON 12-IN CENTERS. EACH DOWEL IS INSTRUMENTED WITH STRAIN GAGES TO MEASURE BENDING MOMENT ALONG THE DOWEL AND SHEAR TRANSMITTED ACROSS THE JOINT. MOMENT, SHEAR, AND PRESSURE CURVES ARE PRESENTED FOR ALL DOWELS IN THE JOINT FOR A WHEEL LOAD OF 50,000 LB APPLIED AT THE CENTER OF THE SLAB TANGENT TO ONE FACE OF THE JOINT. SLAB DEFLECTIONS ARE MEASURED WITH MECHANICAL DIAL INDICATORS AND COMPLETE TRANSVERSE AND LONGITUDINAL CONTOURS ARE PRESENTED. RESULTS OF THE APPLICATION OF TEST RESULTS TO CURRENT DESIGN EQUATIONS ARE PRESENTED. /AUTHOR/
