TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways provides suggested guidelines for the application of preservation treatments on high-volume roadways. The guidelines consider traffic volume, pavement condition, work-zone requirements, environmental conditions, and expected performance.

Errata (October 2011): Table 3.2 (pp. 20-21) contained incorrect information in the following rows: chip seal (single); chip seal (double); and hot in-place recycling. The table has been corrected in the online version of the guide.

The same project that produced SHRP 2 Report S2-R26-RR-2 also produced SHRP 2 Report S2-R26-RR-1: Preservation Approaches for High-Traffic-Volume Roadways, which documents the state of the practice of preservation treatment on asphalt and concrete pavements. The report focuses on treatments suitable for application on high-traffic-volume roadways but also discusses current practices for low-volume roadways.
