KNOWLEDGE-BASED EXPERT SYSTEM TECHNOLOGY CAN BENEFIT PAVEMENT MAINTENANCE

Timely and judicious selection of pavement maintenance treatments can significantly extend pavement life. To facilitate this task, an expert system for recommending routing and sealing (ROSE) of asphalt concrete pavements in cold areas was developed. The system incorporates data transmitted by 41 variables, such as pavement serviceability, age, and types of pavement surface distress, and encodes expertise derived from recent research and development studies and from experience. It contains about 360 rules. The system recommendations are given as a desirability of routing and sealing on a scale from 0 to 10. The interactive version of ROSE was developed and calibrated using an expert system development shell. This resulted in significant savings in programming, testing, and calibration. An automatic version of ROSE was implemented in FORTRAN and successfully applied to about 900 pavement sections, representing about 7200 km of highway. This application makes it possible to quantify funding requirements for different routing and sealing policies.
