REHABILITATION DECISION MODEL

A study was made of Utah's flexible pavement performance system to introduce new procedures and to alter existing procedures. The terminal serviceability concept was revised to consider functional class as well as average daily traffic. Highways with high average daily traffic were assigned a high terminal serviceability index to reduce user costs. A computerized pavement-rating system was developed to aid maintenance personnel in making the most appropriate pavement rehabilitation decision. The system can also be used by planning and programming personnel to estimate future expenditures in each district. A computer program generates priority listings based on the failure modes of serviceability, distress, structural adequacy, and skid resistance. An overall listing is produced that considers failure modes with respect to average daily traffic, 80-kN (18-kip) loads, running speeds, and functional class. /Author/
