Recent changes in the Highway Performance Monitoring System (HPMS) related to pavements and Moving Ahead for Progress in the 21st Century Act (MAP-21) requirements for pavement performance measures have heightened the importance of having, maintaining, and using an effective pavement management system (PMS). Most states have implemented a pavement management system (PMS) but they now face new challenges. Data collection has moved from primarily windshield surveys to automated collection. Data analysis can be manual, semi-automated, or automated. PMS engineers are asked to provide consistent, dependable analysis in the face of changing technologies and budgetary restrictions. The purpose of this synthesis is to document the state-of-the-practice for pavement management systems used by departments of transportation (DOTs). The synthesis will be useful to DOTs that are considering making changes to their PMS to enhance the usability of their data and to better manage their pavement assets with limited resources. |
