Many conventional preservation techniques–and some new ones–can be used to extend the life of high-traffic roadways without major reconstruction and traffic disruption. Guidelines for the Preservation of High-Traffic-Volume Roadways (R26) offers the technical background and decision-making framework needed to bring preservation strategies widely into play for high-traffic roads.

Developed through the second Strategic Highway Research Program (SHRP2), these are the first systematic and comprehensive resources designed to expand the use of pavement preservation on high-traffic roads.

• Preservation Analysis Tool
• Preservation Analysis Tool Instructions
• Preserving High-Traffic Roadways – overview brochure
• Data Collection Guide
• Just-In-Time Training
  • These Just-In-Time Training modules address numerous pavement preservation topics, from general content on project selection, treatment selection, and pavement evaluation, to specific details on treatments for high-traffic-volume roadways. The modules are organized into overview topics, followed by detailed training on techniques to preserve asphalt and concrete-surfaced pavements.
  • Each topic takes around 5 to 15 minutes to complete. The modules can be taken as a series or as stand-alone lessons and are designed to help teams access the content they need from just about anywhere.
