May 13, 2014, Lanham, Md. — As public works agencies and
departments of transportation look to make the most efficient use of tight
budgets, the National Asphalt Pavement Association is outlining the benefits of
Thinlay thin asphalt mixtures for pavement preservation. Thinlays are a suite
of thin asphalt overlay mixes designed to be placed at thickness as thin as 5/8
of an inch.

May 13, 2014, Lanham, Md. — As public works agencies and
departments of transportation look to make the most efficient use of tight
budgets, the National Asphalt Pavement Association is outlining the benefits of
Thinlay thin asphalt mixtures for pavement preservation. Thinlays are a suite
of thin asphalt overlay mixes designed to be placed at thickness as thin as 5/8
of an inch.

 

The association, working with state asphalt pavement
associations and the National Center for Asphalt Technology, is testing several
localized Thinlay mixes with a high level of recycled materials, which will be
used to craft guidelines other states can use to develop sustainable thin
overlays designed to best meet their local needs, conditions, and materials.

 

Thinlays offer the highest value to public and private
pavement owners alike. They share many of the benefits seen in asphalt overlays
and inlays: extended pavement life, smooth ride, a modest improvement in
pavement strength, enhanced safety, and responsible use of natural resources
through reuse and recycling.

 

A new paper from NAPA, “Thinlays: The Pavement Preservation
Tool of Choice,” outlines the benefits of Thinlays, documenting their benefits
and the important role they can play as part of a pavement maintenance program.
