Computational Framework for Pavement Sensitivity Analysis Using the Mechanistic Empirical Pavement Design Procedure

Abstract

In civil engineering, the performance of a structure or project is the main objective. When designing a particular project it is important to explore an array of design options to determine which will perform best. This approach applies well to road design. Roads have many different characteristics that can be varied, from the thickness of different layers to the AADTT (average annual daily truck traffic). For this project a sensitivity analysis was performed to determine how particular output criteria would respond to variation in particular input variables. This analysis is done exclusively using computer modeling by the use of an array of programs.
