Synthesis of Information Related to Highway Problems. Topic 41-01. Geometric Design Practices for Resurfacing, Restoration, and Rehabilitation

In response to a provision in the Surface Transportation Assistance Act of 1982, the Transportation Research Board studied the safety and cost effectiveness of highway geometric design standards and recommended minimum standards for Resurfacing, Restoration and Rehabilitation (RRR) projects on existing federal-aid highways, except for freeways. In 1987, The Transportation Research Board (TRB) published Special Report 214, Designing Safer Roads: Practices for Resurfacing, Restoration, and Rehabilitation." The American Association of State Highway Transportation Officials (AASHTO) subsequently amended the Foreword of the Policy on Geometric Design for Highways and Streets to include the following sentence: "This publication is not intended as a policy for Resurfacing, Restoration, or Rehabilitation (3R) projects and refers the reader to TRB Special Report 214 for design guidance." In 2001, AASHTO published Guidelines for Geometric Design for Very-Low Volume Local Roads (ADT ≤ 400). While this document does not specifically address RRR work, it does provide some guidance related to improving the safety and cost-effectiveness of geometric design for existing, low-volume roads. With TRB SR 214 specifically addressing RRR work on federal-aid highways and AASHTO providing limited guidance only on roads with ADT less than 400 vehicles per day, there is a lack of design guidance for RRR work on the wide range of roads that have traffic volumes in excess of 400 vehicles per day but are not eligible for federal-aid funding. A need exists to document the state of highway practice related to resurfacing, restoration, and rehabilitation (3R) design guidelines for these roadway types. State transportation agencies in Alabama, California, Florida, Kansas, North Carolina, Oregon, and Texas all have 3R design guidelines; however, all are different. It is therefore likely that the range of current practice is considerable. The main focus of this project should be to conduct a state transportation agency survey to document current practices related to 3R design. The synthesis should document the range of 3R design practices used by state transportation agencies in the United States. This product of this synthesis will be of considerable value to local transportation agencies in need of a document that highlights best practices of 3R design policies currently used in the U.S. Information will be gathered by literature review, survey of transportation agencies, and selected interviews.
