Pavement preservation is broadly acknowledged to provide network-wide benefits such as extending pavement life, enhancing system performance, reducing operation and maintenance costs, and improving safety. However, the performance of each pavement preservation project hinges on many factors.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 565: Maintenance and Surface Preparation Activities Prior to Pavement Preservation Treatments documents the types of maintenance and surface preparation activities performed by departments of transportation before pavement preservation treatments are applied.
