Rejuvenating Asphalt Products

The objective of this investigation is to provide recommendations for creating a performance based specification for rejuvenating and surface sealing products that extend asphalt pavement life. The product evaluation will consider the effectiveness of softening the existing asphalt binder, improving the existing rheological properties (less brittle), and decreasing the permeability of the pavement. The product comparisons will outline the pros and cons to include, but not limited to: the testing results, cure time necessary before opening roadway to traffic, daily production rate, material cost, material location, other economical limitations, application rate utilized and blotting materials utilized, if applicable. A field application study will be performed and evaluated by a third party researcher to provide a report of each product’s performance.
