A SENSITIVITY ANALYSIS OF FLEXIBLE PAVEMENT SYSTEM FPS2

FLEXIBLE PAVEMENT SYSTEM FPS2 IS A DESIGN CONCEPT FORMULATED INTO A COMPUTER PROGRAM WHICH ANALYZES FLEXIBLE PAVEMENTS UTILIZING AN OVERALL SYSTEMS APPROACH TO THE PROBLEM. A SENSITIVITY ANALYSIS WAS PERFORMED (1) TO ESTABLISH THE RELATIVE IMPORTANCE AND COST SENSITIVITIES OF THE DIFFERENT VARIABLES ON THE SYSTEM, (2) TO STUDY CHANGES IN THE STRUCTURAL DESIGNS GENERATED DUE TO CHANGES IN THE VARIABLE VALUES, AND (3) TO DEBUG THE PROGRAM IN ORDER TO FIND ANOMALIES AND PROBLEM AREAS. THREE BASIC SOLUTIONS WERE OBTAINED AT THREE BASIC LEVELS OF THE VARIABLES; LOW, AVERAGE, AND HIGH. THE SENSITIVITY OF EACH VARIABLE WAS STUDIED AT EACH OF THESE THREE BASIC LEVELS BY CHANGING THE VALUE OF THE PARTICULAR VARIABLE TO THE OTHER TWO LEVELS. A TOTAL OF OVER 400 PROBLEMS WERE SOLVED. EACH PROBLEM WAS ANALYZED CAREFULLY FOR THE OVERALL COST OF THE OPTIMAL DESIGN AND ITS DIFFERENT COST CONSTITUENTS, DESIGN THICKNESS, AND NUMBER OF FEASIBLE DESIGNS GENERATED. BASED ON THE DESIGN AND COST SENSITIVITIES, THE VARIABLES PRODUCING SIMILAR EFFECTS WERE GROUPED TOGETHER. THE VARIABLES WERE IN THE ORDER OF THEIR IMPORTANCE WITH RESPECT TO THE OVERALL COST OF THE OPTIMAL DESIGN. /FHWA/
