A survey was conducted of resurfacing, restoration, and rehabilitation (RRR) type programs throughout the United States. RRR practices of state highway departments were solicited, with emphasis on seeking cost-effective designs that maintained acceptable levels of safety and serviceability. The reported RRR actions by various states are summarized, and the primary rulings on RRR design standards are briefly discussed. A philosophy tailored toward maximum mileage standards, accompanied by the application of value engineering, forms the basis of many RRR state policies. In every case, safety was found to be of primary concern. Three general philosophies appear applicable based on this RRR review:(a) rehabilitation to standards below full AASHTO new construction standards, and correcting major defects but maximizing the number of miles of highway treated;(b) reconstruction to full AASHTO standards only, for greater safety on fewer miles of roads; and (c) full funding for all projects as an ideal. Preliminary safety studies are reviewed, and guidelines are presented for maximum mileage rehabilitation projects drawn from the state surveys=

Under a recent contract with the Auditor General's Office, State of Arizona, the Texas Transportation Institute (TTI) had the opportunity to survey resurfacing, restoration, and rehabilitation (RRR) type programs throughout the United States. The objective of the study was to provide a summary of RRR practices reported by state highway departments. Empha-
