Geometric Design Practices for Resurfacing, Restoration, and Rehabilitation - A Synthesis of Highway Practice

Each state transportation agency has its own design guidance and standards for nonfreeway resurfacing, restoration, and rehabilitation (3R) projects. These include enhancements to improve highway safety. The purpose of this study was to gather and synthesize current state practices related to 3R projects. Information was acquired through a literature review and a survey of all state transportation agencies. Documents that provide state 3R policies were obtained either from state websites or directly from the states.
