Author: D. Peshkin, K. L. Smith, A. Wolters, J. Krstulovich, J. Moulthrop, C. Alvarado | Size: 1 MB | Format: PDF | Publisher: TRB | Year: 2011 | pages: 62 | ISBN: 9780309128926

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.
