  Thin-lift overlays for pavement preservation growing in popularity; free webinar on ‘Thinlay’ strategy set for Nov. 28
A new generation of thin-lift asphalt overlays called Thinlays™ are  rapidly becoming 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.

The National Asphalt Pavement Association (NAPA), a MAA partner, continues to offer practical guides and information to help pavement designers learn more about this pavement strategy.

“Thinlay Pavement Preservation: A Contractor’s Perspective” is the title of a free webinar being put on by NAPA on Wednesday, Nov. 28 from 2:00 – 3:30 p.m. EDT. The guest speaker will be Chuck Fuller, Industry Relations Consultant, Texas Asphalt Pavement Association.

This webinar, drawing upon practical knowledge from experienced contractors, will focus on proper application of Thinlays to achieve the highest performing pavement preservation solution for pavement owners. Among the areas to be covered:

  • Understanding Thinlay specification requirements (Specific-use programs (e.g. Texas Thin Overlay Mixtures, Ohio Smoothseal)
  • Site Conditions and Prep Work
  • Tack – Bond – Seal
  • Construction Best Practices
  • Project Examples

To register for this webinar on-line, click HERE. NAPA has compiled additional Thinlay resources HERE.

The webinar comes on the heels of the recent release by NAPA of a new technical publication about the effective use of thin-life asphalt pavement overlays.

The publication, titled “Thinlays for Pavement Preservation” (IS-141E) is available as a free download for government agencies. Click HERE to learn more and download the publication.

The guide provides comprehensive guidance on using Thinlays, including how Thinlays fit within pavement management systems, when and how they should be used based on existing pavement condition, how Thinlay mixes should be developed and specified, and best practices for Thinlay construction.

Professional Development Hours (PDHs):
Attendees will receive 1.5 hours of professional development for participating in this webinar.

 

The guide also helps users compare the cost and performance of common pavement preservation techniques. More technical publications can be found at the NAPA on-line store HERE.
