TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R26-RR-2: Guidelines for the Preservation of High-Traffic-Volume Roadways explores the state of the practice for preservation treatments on high- and low-volume asphalt and concrete roadways. The report also includes suggested guidelines on the application of preservation treatments on high-volume roadways.
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 on high- and low-volume roadways.
