Pavement Preservation for High Traffic Volume PCC Roadways: Phase I Findings From SHRP 2 Project R26

The practice of pavement preservation in general, and preventive maintenance in particular, is a growing trend among transportation agencies around the United States. However, the practice of preservation on high traffic volume roadways is not as well documented as it is on lower volume roadways. Nonetheless, the preservation of high traffic volume roadways is as important as the preservation of lower traffic volume roadways. Under the direction of SHRP 2, Project R26, Preservation Approaches for High Traffic Volume Roadways, was initiated to assess the state of the practice and to provide guidance on pavement preservation for high traffic volume roadways. The ultimate outcome of this study is the development of guidelines that lead to higher volume roadways being maintained in serviceable condition for longer periods of time before rehabilitation is needed, at a lower cost, in a safer manner, and with less disruption to the traveling public. A secondary objective of this study is to identify promising pavement preservation strategies for application on high traffic volume roadways that might not commonly be used, and to make recommendations for further research opportunities. As part of the first phase of this study, a 24-question survey of practice was distributed to all state highway agencies and Canadian provinces, as well as selected large cities and several agencies in other countries. Ultimately, 57 responses were received. While survey questions addressed both hot-mix asphalt and portland cement concrete (PCC) pavements, this paper focuses on the responses related to pavement preservation on PCC pavements.
