About the Project
The Client's Goal
Develop and calibrate initial performance models for Alaska Department of Transportation and Public Facilities' (DOT & PF) pavement management system (PMS) so the agency can predict performance and funding needs with greater confidence.
Our Work
Reviewed existing pavement condition data.
Organized condition data into databases linked with pavement management road segments for more accurate modeling.
Assisted the agency with defining representative pavement families and included this information in the condition databases for modeling analyses.
Worked with the PMS vendor to define reasonable and appropriate pavement families and generate performance models for rutting, longitudinal profile (IRI), and cracking that were coded into the PMS.
Coordinated with the PMS software vendor to ensure compatibility between the software, the pavement families, and the performance models.
Documented efforts in a comprehensive project report.
The Outcome
Due to APTech’s efforts, the Alaska DOT&PF was able to use historic condition data and recent cracking data to develop performance models in its new statewide PMS. Now the agency can generate reasonable projections of performance and better estimates of maintenance and repair work needs.
