KNOWLEDGE-BASED EXPERT SYSTEM TECHNOLOGY CAN BENEFIT PAVEMENT MAINTENANCE

This report describes an expert system called "rose", developed for the programming of routing and sealing of asphalt concrete pavements in cold areas. The system incorporates 40 numberical variables, such as pavement serviceability, age and pavement surface distresses, and contains about 360 rules. The system recommendations are given as a desirability of routing and sealing on a scale from 0 to 10. It encodes expertise derived from recent research and development studies and from experience. The interactive version of rose was developed and calibrated using an expert system development shell (exsys). An automatic version of rose was implemented in FORTRAN and successfully applied to about 900 pavement sections, representing about 7200 highway kilometers. (Author/TRRL)
