SHRP2 R26—”Preservation of High-Traffic-Volume Roadways”

Project R26, “Preservation Approaches for High-Traffic-Volume Roadways”, was an approximately 2-year study of agency pavement preservation practices conducted as part of SHRP2.  Completed in 2011, the published guidelines address pavement preservation activities for roadways with high traffic volumes and provide extensive guidance on selecting good candidate roadways and preservation treatments.  Formal implementation efforts by state highway agencies began in 2012 with support from FHWA, AASHTO, and TRB.  Additional information about the original research, implementation initiatives, and other SHRP2 research can be found at www.fhwa.dot.gov/goshrp2.
