EXPERIMENTAL AND THEORETICAL STUDIES OF PAVEMENT BEHAVIOUR UNDER VEHICULAR LOADING IN RELATION TO ELASTIC THEORY

THE PAPER DESCRIBES A SERIES OF EXPERIMENTS TO DETERMINE THE DEGREE TO WHICH MULTI-LAYER ELASTIC THEORY CAN BE USED TO PREDICT STRESSES, STRAINS, AND DEFLECTIONS OF PAVEMENTS UNDER MOVING VEHICLES. MEASUREMENTS OF STRESS AND DEFLECTION IN FLEXIBLE PAVEMENTS OF REALISTIC DESIGN HAVE BEEN MADE UNDER PILOT-SCALE CONDITIONS OVER A WIDE RANGE OF WHEEL LOADS, SPEEDS, AND TEMPERATURES, AND SIMILAR TESTS HAVE ALSO BEEN CARRIED OUT ON A SIMPLE CONCRETE SLAB. RESULTS ARE PRESENTED AND COMPARED WITH THOSE PREDICTED FROM MULTI-LAYER ELASTIC THEORY. THE RESULTS SHOW THAT ELASTIC THEORY CAN BE USED TO PREDICT THE DYNAMIC BEHAVIOR OF RELATIVELY STIFF PAVEMENTS, BUT THAT DEVIATIONS OCCUR UNDER HIGH TEMPERATURE CONDITIONS. /AUTHOR/
