Guidelines for the Preservation of High-Traffic-Volume Roadways

This issue explores the state of the practice for preservation treatments on high- and low-volume asphalt and concrete roadways. The report includes suggested guidelines on the application of preservation treatments on high-volume roadways.

SHRP 2 focuses on applied research in four focus areas:
• Safety, to prevent or reduce the severity of highway crashes by understanding driver behavior;
• Renewal, to address the aging infrastructure through rapid design and construction methods that cause minimal disruptions and produce lasting facilities;
• Reliability, to reduce congestion through incident reduction, management, response, and mitigation;
• Capacity, to integrate mobility, economic, environmental, and community needs in the planning and designing of new transportation capacity.
