In recent years, transportation agencies have turned to pavement preservation as a key strategy to extend the life and improve the condition of their roadway networks. With many agencies now facing decreased capital budgets, it will become critical to keep good roads in good condition. Preservation treatments and approaches will be even more important in the future, therefore, as relatively small investments in preservation activities can significantly increase infrastructure life. However, the use of many available strategies has been restricted to roadways experiencing lower traffic volume, with little use on high-volume roads.
A new report issued by the Second Strategic Highway Research Program (SHRP 2), Guidelines for the Preservation of High-Traffic-Volume Roadways, provides information to help expand agencies’ ability to use varied treatments to best meet the preservation needs on higher-volume roadways. The report is the result of research performed under SHRP 2 Renewal Project R26: Preservation Approaches for High-Traffic-Volume Roadways.
