THE PRINCIPLE OF SUPERPOSITION IN PAVEMENT ANALYSIS

THE PRINCIPLE OF SUPERPOSITION WAS USED IN ANALYSIS OF INSTRUMENTATION DATA OBTAINED IN TEST SECTIONS CONSTRUCTED AT THE WATERWAYS EXPERIMENT STATION. INCLUDED WERE HOMOGENEOUS SAND AND CLAYEY SILT TEST SECTIONS UNDER PLATE LOADS AND THE MILTIPLE-WHEEL HEAVY GEAR LOAD FLEXIBLE PAVEMENT TEST SECTIONS UNDER SINGLE-AND MULTIPLE-WHEEL LOADS . IT IS FOUND THAT THE PRINCIPLE OF SUPERPOSITION IS APPROXIMATELY VALID, INDICATING LINEAR THEORY IS NOT UNREASONABLE IN APPLICATION TO PAVEMENT ANALYSIS, ALTHOUGH LABORATORY TESTS HAVE DEFINITELY PROVED PAVEMENT MATERIALS BEHAVE NONLINEARLY UNDER LOADS. THE AUTHORS CANNOT ANSWER THE PROBLEM; THE CENTRAL PURPOSE OF THIS PAPER IS TO STIMULATE DISCUSSIONS BY OTHER RESEARCHERS THAT WILL AID IN PAVEMENT ANALYSIS.
