Cost Effective Alternatives to Seal Coats

The primary focus of this project is the development of a mix design procedure and construction guidelines for an ultra-thin hot mix asphalt (HMA) alternative to seal coats. This project will develop performance tests and implementation guidelines for ultra-thin (approximately 0.5 inch thick or less) asphalt layers intended as an alternative to seal coats (with similar or lower lifecycle cost). The project will also address the mix design and testing of ultra-thin layer mixes both in the field and in the laboratory towards the selection of appropriate performance tests to evaluate the life expectancy, aggregate loss, ride quality of new ultra-thin asphalt overlays, and estimated lifecycle cost. Products of this project will be the designing and monitoring of demonstration projects for ultra-thin asphalt layers, curriculum for a training program that introduces personnel to ultra-thin asphalt overlays, a technical memoranda and research report which documents the materials and construction specification for ultra-thin overlays, and a project summary report.
