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.
