The pacific northwest region of the usda forest service manages some 3, 600 mi of low-volume paved roads. The region has been faced with a need to identify procedures by which the selection and timing of maintenance activities can be ordered by priority for funding purposes. After review of available pavement management systems (pmss), the metropolitan transportation commission's pms (mtc-pms) was found to be appropriate for low-volume road agencies. Developed for the san francisco bay area, the mtc-pms is a computer-assisted method ofanalyzing information about pavement condition for developing cost-effective, long-term maintenance strategies. The implementation of the mtc-pms on low-volume paved roads within the forest service is described. A pilot implementation of the mtc-pms was conducted to determine if the system could meet the pavement management needs of the forest service. In the summer of 1988, pavement condition data were collected on approximately 600 mi of road. A 280-mi paved road network on the siuslaw national forest was analyzed in detail by all of the mtc-pms procedures. The results from the pilot implementation period indicate that the mtc-pms can be used as an effective pavement management tool for the forest service.
