EXPERIMENTAL VERIFICATION OF DISCRETE-ELEMENT SOLUTIONS FOR PAVEMENT SLABS
THE VALIDITY OF ANY ANALYTICAL METHOD CAN BEST BE PROVED BY COMPARING ITS SOLUTIONS WITH ACTUAL TEST RESULTS. TO OBTAIN SPECIFIC TEST RESULTS FOR USE IN VERIFICATION OF THE DISCRETE-ELEMENT METHODS, A STUDY OF SMALL-DIMENSION SLAB- ON-FOUNDATION UNDER CONTROLLED CONDITIONS WAS CONDUCTED. AN INSTRUMENTED ALUMINUM SLAB 9 BY 9 BY 1/8 IN. WAS TESTED RESTING ON A SPECIALLY PREPARED SATURATED CLAY SUBGRADE UNDER 2 LOADING POSITIONS. PLATE-LOAD TESTS WERE PERFORMED TO DETERMINE LINEAR AND NONLINEAR CHARACTERISTICS OF THE SOIL FOR REPRESENTING THE SUBGRADE ACCORDING TO THE WINKLER ASSUMPTION. THESE CHARACTERISTICS WERE ALSO DETERMINED FROM STRESS -- STRAIN RELATIONS OF THE SOIL, OBTAINED FROM UNCONFINED COMPRESSION TESTS. A COMPARISON OF DISCRETE- ELEMENT SOLUTIONS AND EXPERIMENTAL RESULTS WAS MADE FOR DEFLECTIONS, PRINCIPAL STRESSES, AND STRESSES ALONG THE EDGE FOR DIFFERENT LOADS. THE TESTS CONFIRM THAT THE DISCRETE- ELEMENT SOLUTIONS CAN BE USED WITH CONFIDENCE TO OBTAIN SATISFACTORY SOLUTIONS FOR PAVEMENT SLABS. /AUTHOR/
