Users Guide to the Highway Concrete (HWYCON) Expert System

One of the major goals of the Strategic Highway Research Program (SHRP) was to improve the performance and durability of highway concrete. SHRP Project C-206, Optimization of Highway Concrete Technology, was created to disseminate knowledge of the results of SHRP-sponsored research and recent advancements in concrete materials technology. The products of this project included a synthesis of advances in highway concrete technology, training videos, and the expert system HWYCON (Highway Concrete). HWYCON is designed to assist state highway departments in three areas: 1) diagnosing distresses in highway pavements and structures; 2) selecting materials for construction and reconstruction; and 3) obtaining recommendations on materials and procedures for repair and rehabilitation methods. HWYCON is an operational system and will be distributed to state departments of transportation through SHRP. This document is intended to provide a reference for users of the system who need information about the knowledge base, installation, and operation of HWYCON.
