A PAVEMENT REHABILITATION EXPERT SYSTEM (PARES) FOR PRELIMINARY DESIGN. FINAL REPORT

The objective of this research effort was to develop a computerized expert system that could be used to assist the New Mexico State Highway and Transportation Department's Planning Bureau and Materials Lab Bureau in the evaluation and development of rehabilitation schemes for flexible pavements. This code is termed PARES (PAvement Rehabilitation Expert System) for preliminary pavement design. The knowledge base of PARES is comprised of 278 rules which reason about 23 different distress types in an effort to select one or more of 21 different rehabilitation strategies. The expert system interacts with other numerical codes, including a module to assess relative costs of the recommended rehabilitation strategies. The system as configured eventually would use information collected from the Department's pavement management system and consolidated database to establish initial rehabilitation schemes (based on current AASHTO design procedures) that would be reasonable and cost effective. Products of the project consist of: (1) an implemented "VAX" computer-based integrated system software package for the preliminary rehabilitation design of flexible pavements, (2) a final report, and (3) a user's manual documenting the software. The system is installed on the State's VAX-cluster.
