A MODEL STUDY OF RIGID PAVEMENT BEHAVIOR UNDER CORNER AND EDGE LOADINGS

RESULTS OF LABORATORY TESTS, USING SMALL SCALE MODELS, ARE PRESENTED AND COMPARED WITH THEORETICAL ANALYSES OF CRITICAL STRESSES RESULTING FROM SINGLE-WHEEL LOADS ACTING AT A FREE CORNER AND AT A FREE EDGE OF A RIGID PAVEMENT SLAB. INCLUDED ARE A BRIEF DESCRIPTION OF THE DESIGN AND CONSTRUCTION OF THE MODEL, TEST PROCEDURES USED, PRESENTATION OF THE DATA THEREFROM AND ITS ANALYSIS. PRINCIPALLY, THE TESTING INVOLVED MEASURING STRAINS IN A PLASTER SLAB SUBJECTED TO STATIC LOADING AS FOLLOWS: (1) LOADS TANGENT TO A FREE EDGE AND AT A CONSIDERABLE DISTANCE FROM ANY CORNER; AND (2) LOADS TANGENT TO BOTH EDGES OF THE SLAB AT A FREE CORNER. BY USING VARIOUS SIZES OF BOTH CIRCULAR AND ELLIPTICAL CONTACT AREAS IN LOADING THE SLAB, AND EXPRESSING THE STRESS COMPARISONS IN NON-DIMENSIONAL TERMS, RELATIONSHIPS BETWEEN CRITICAL PAVEMENT STRESSES FOR CORNER AND EDGE LOADINGS ARE ESTABLISHED WHICH ARE APPLICABLE TO THE PROTOTYPE AS WELL AS TO THE MODEL. /AUTHOR/
