• Abstract:
  It costs less to maintain roads in good condition than in poor condition. Pavement preservation is a set of ; activities to extend pavement life, improve safety, and meet road user expectations. Surface treatments are ; pavement preservation treatments applied to the whole surface of the road. This synthesis summarizes surface ; treatments’ state of practice in the United States, especially southeastern states. Eleven pavement preservation ; techniques were addressed: fog seal, rejuvenator seal, chip seal, sandwich seal, scrub seal, slurry seal, ; microsurfacing, cape seal, thin overlays, ultrathin bonded wearing course and crack sealing/filling. Recent ; work on surface treatments has been reviewed and summarized. To research surface treatments’ state of ; practice, a survey was designed and distributed to Southeastern Association of State Highway and ; Transportation Officials (SASHTO) agencies. Nineteen participants from Florida, Georgia, Louisiana, ; Virginia, West Virginia, North Carolina, and Arkansas participated in the survey. The electronic survey ; consisted of three questionnaires asking administrative, technical, and research-related questions. Results ; showed that thin overlays, crack repairs, microsurfacing, chip seal, and fog seal are the most common ; preventative maintenance practices. In this report, each chapter is dedicated to one surface treatment ; technique. Chapters start with a description of the technique, its applications, features, material and equipment ; requirements, and construction procedures. This is followed by a summary of recent work and implementation ; status, as obtained from the survey.
