Pavement preservation ensures that roads last longer at a lower cost compared to traditional maintenance treatments such as mill and fill. There are several guidelines that discuss the right treatment for the right road at the right time. However, even when everything is done right, supplemental maintenance activities are often required to ensure that the treatment will perform successfully. These proactive maintenance activities can include crack sealing, patching, leveling, drainage repair, and rut filling or removal.
The objective of this synthesis is to document the types of maintenance activities performed by DOTs before pavement preservation treatments are applied. Information to be gathered includes the types of maintenance activities required, the length of time between the maintenance actions and applying the preservation treatments, who usually performs the maintenance, and available metrics linking maintenance activities to performance of the pavement preservation.
Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
