A SENSITIVITY ANALYSIS OF FLEXIBLE PAVEMENT SYSTEM FPS2

FLEXIBLE PAVEMENT SYSTEM FPS2 IS A DESIGN CONCEPT FORMULATED INTO A COMPUTER PROGRAM THAT ANALYZES FLEXIBLE PAVEMENTS BY UTILIZING AN OVERALL SYSTEMS APPROACH TO THE PROBLEM. THE PROGRAM USES 45 DIFFERENT TYPES OF INPUTS IN THE BROAD CATEGORIES OF DESIGN CONSTRAINTS, DESIGN VARIABLES, AND COST VARIABLES. THE DESIGN ALTERNATIVES ARE ANALYZED BY USING ECONOMIC CONCEPTS. THIS REPORT DESCRIBES A SENSITIVITY ANALYSIS PERFORMED TO ESTABLISH THE RELATIVE IMPORTANCE AND COST SENSITIVITIES OF THE DIFFERENT VARIABLES OF THE SYSTEM, STUDY CHANGES IN THE STRUCTURAL DESIGNS GENERATED DUE TO CHANGES IN THE VARIABLES VALUES, AND COMPLETELY DEBUG THE PROGRAM TO FIND ANOMALIES AND PROBLEM AREAS. AN EXPERIMENT IS ESTABLISHED TO OBTAIN THE REQUIRED INFORMATION. THREE BASIC SOLUTIONS ARE OBTAINED AT THREE BASIC LEVELS OF THE VARIABLES; LOW, AVERAGE, AND HIGH. THE SENSITIVITY OF EACH VARIABLE IS 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 IS SOLVED FOR THIS ANALYSIS. IT IS CONCLUDED THAT FPS2 GENERALLY GIVES REASONABLE SOLUTIONS; THE VARIABLES ARE SENSITIVE TO VARIOUS DEGREES WITH RESPECT TO COSTS AND STRUCTURAL DESIGNS, AND THE TRAFFIC AND MATERIAL PROPERTIES ARE THE MOST IMPORTANT PARAMETERS OF THE SYSTEM. /AUTHOR/
