Thin Is In for Pavement Preservation

Thin asphalt overlays are a popular approach to pavement preservation because of their ability to provide improved ride quality, reduce pavement distresses, maintain surface geometrics, reduce noise levels, reduce life-cycle costs, and provide long-lasting service. Recently, NAPA helped organize a thin asphalt overlay using warm-mix asphalt and recycled materials in Nashville, Tenn.

 

 

Tenth Street in downtown Nashville, an urban pavement with many utility cuts, was given 10 years more of life with this green (economically and environmentally) thin asphalt overlay preservation treatment. This is a NAPA instructional demonstration for those interested in asphalt paving processes and procedures. Mike Huner, Director of Technical Services for the Tennessee Road Builders Association, is the presenter. Special thanks go to the contractor, LoJac Enterprises Inc. of Lebanon, Tenn. The Tenth Street project was completed in August 2012. For more information on thin asphalt overlays, visit www.asphaltpavement.org/ThinIsIn.
