SENSITIVITY ANALYSIS OF THREE RIGID PAVEMENT DESIGN TECHNIQUES
Three rigid pavement design techniques were studied to determine the relative effects of various design parameters on pavement thickness. The analysis phase of this investigation consists 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 1 theoretical and 2 practical measures of parameter importance. The theoretical measure reveals considerable differences among techniques as to the process of resolving design thicknesses and as to the relative theoretical influence of various parameters that estimate the same major design factors. Practical measures of parameter importance, which amount for variations in parameter values as well as the manner in which the design variables are formulated in the thickness model, show a greater consistency in the importance of generic factors among design methods. Although the relative importance of the traffic load differs with the 3 design methods investigated, this parameter and the flexural strength are the influential factors in the design of rigid pavement thicknesses.
