Advisory expert system for flexible pavement design

Abstract The adoption of an expert system approach to flexible pavement design could be especially useful, because of the complexity of the design algorithm involving numerous possible combinations of pavement material types and traffic data, and the heavy reliance on empirical correlations, which can vary from one region or state to another. This paper describes the development of an advisory expert system for flexible pavement design that attempts to mimic the design process of pavement engineering specialists. The highly interactive microcomputer expert system was developed, using an expert system shell.
