The 1985 AASHTO nomograph and equations for flexible pavements were reviewed and analyzed to determine requirements for input data, sensitivity of designs based on the additional variables for percent reliability, standard deviation, and resilient modulus of subgrade material. Design thicknesses using the 1985 AASHTO Guide were compared to thicknesses using the 1981 Kentucky thickness design method for flexible pavements.
