SOME PROBLEMS IN THEORETICAL ANALYSIS OF PAVEMENT STRUCTURES

THE U.S. AIR FORCE WISHES TO DEVELOP A SINGLE EVALUATION TECHNIQUE APPLICABLE TO BOTH RIGID AND FLEXIBLE AIRFIELD PAVEMENTS. THE TECHNIQUE SHOULD (1) PREDICT THE LOAD- CARRYING CAPACITY AND EXPECTED SERVICE LIFE OF EXISTING AIRFIELD PAVEMENTS AND OVERLAYS, (2) EVALUATE THE EFFECT OF REPETITIVE LOADINGS, AND (3) DETERMINE THE STRESSES AND STRAINS AT ANY POINT IN PAVEMENT SYSTEM ATTRIBUTABLE TO ANY GEAR CONFIGURATION. IN THIS PAPER THE CAPABILITIES AND LIMITATIONS OF THREE COMPUTER PROGRAMS, ALL OF WHICH IDEALIZE BOTH TYPES OF PAVEMENTS AS LAYERED STRUCTURES, ARE EXAMINED TO DETERMINE THEIR SUITABILITY AS AN ANALYTIC MODEL FOR USE IN RATIONAL PAVEMENT EVALUATION. COMPUTED RESULTS ARE COMPARED WITH TEST DATA, A CODE UTILIZING A FINITE ELEMENT METHOD IS RECOMMENDED, AND REQUIRED MODIFICATIONS TO THAT CODE ARE INDICATED.
