THE OPTIMIZATION OF A FLEXIBLE PAVEMENT SYSTEM USING LINEAR ELASTICITY

THIS REPORT INTEGRATES LINEAR ELASTIC THEORY INTO THE CURRENT VERSION OF THE TEXAS FLEXIBLE PAVEMENT DESIGN SYSTEM IN ORDER TO GIVE AN OBJECTIVE ANALYSIS BASE FOR THE STRUCTURE FEASIBILITY DETERMINATION BASED ON THE INTERNAL STRESSES AND SURFACE DEFLECTIONS CAUSED BY A DUAL-WHEEL LOAD OF 9,000-LB. INCLUDED IN THE REPORT ARE: (1) LAYERED PAVEMENT STRUCTURE UNDER DUAL-WHEEL LOAD, (2) STREAMLINED COMPUTER PROGRAM FOR THE ANALYSIS OF ELASTIC LAYERED SYSTEMS, (3) MULTI-DIMENSION SPLINE INTERPOLATION, (4) REGRESSION OF TEXAS TRIAXIAL MODEL BASED ON FIBONACCI SEARCH, (5) MEANS FOR CHECKING THE STRUCTURE FEASIBILITY OF MATERIALS, AND (6) TWO EXAMPLES OF THE USE OF FPS-BISTRO. /NTIS/
