Preservation Approaches for High-Traffic-Volume Roadways

This report documents the state of the practice of preservation treatment on asphalt and concrete pavements on high- and low-volume roadways. The report also report includes general guidelines on the application of preservation treatments on high-volume roadways.

The report also 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.
