SENSITIVITY ANALYSIS OF THREE FLEXIBLE PAVEMENT DESIGN TECHNIQUES

THREE HIGHWAY DESIGN TECHNIQUES WERE STUDIED TO DETERMINE THE RELATIVE EFFECTS OF VARIOUS DESIGN PARAMETERS ON PAVEMENT THICKNESS. THE ANALYSIS PHASE OF FORMULATING EACH TECHNIQUE INTO A COMPREHENSIVE MATHEMATICAL OR GRAPHICAL THICKNESS MODEL. AN EVALUATION OF THE INFLUENCES ON THICKNESS OF THE MAJOR DESIGN FACTORS WAS ACCOMPLISHED BY A SENSITIVITY ANALYSIS WITH A THEORETICAL AND TWO PRACTICAL MEASURES OF PARAMETER IMPORTANCE. FOR FLEXIBLE PAVEMENT DESIGN, TRAFFIC LOAD AND SUBGRADE SUPPORT ARE THE MORE INFLUENTIAL FACTORS IN THE DETERMINATION OF PAVEMENT THICKNESS. /AUTHOR/
