Project description

Pavement preservation ensures that roads last longer at a lower cost compared to traditional pavement rehabilitation. Most departments of transportation (DOTs) have established pavement preservation programs. However, even when the right treatment for the right road at the right time is identified, preliminary maintenance and surface preparation activities are often required to ensure that the preservation treatment will perform successfully. These proactive maintenance and surface preparation activities can include crack sealing, patching, leveling, drainage repair, rut filling or removal, and concrete repairs. The objective of this synthesis is to document the types of maintenance and surface preparation activities performed by DOTs before pavement preservation treatments are applied. The synthesis will include both concrete and asphalt pavement preservation treatments. Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. The survey should be directed to the DOT voting members of the AASHTO Committee on Maintenance. Information gaps and suggestions for research to address those gaps will be identified.
