• Abstract:
  Seal coat is a layer of asphalt binder with a layer of aggregate applied over a pavement. The purpose of a seal coat is to seal the pavement from air and water intrusion while providing the safety benefits of maintaining sufficient friction over the seal coat’s design life. With an investment of over $300,000,000 annually, it is imperative to construct a high-quality project. To achieve quality construction, it is important to establish and adjust the application rates for the binder and aggregate based on the materials being used, traffic and existing roadway conditions. This project produced guidelines for improvements to rate design procedures that will help engineers and inspectors make better decisions resulting in successful projects.
