"Best Practice Guidance" Tack Coats How and What to apply! CAPA has developed a technical document that supports the use of best practices for tack material and application. The document discusses tack application rate, materials, surface preparation, application techniques/tracking, and tack setting.
October 2011 Thin Lift Overlay Guidance Use of Thin Lift Overlays Explained Thin lift overlays can be a cost effective tool in the pavement improvement box when pavement structure is needed but there may be tie-in restrictions to curb and gutter. Thin Overlay NAPA Publication; Thin Overlay Sample Specification. For more info
And the Winner is Thin Overlays The FHWA has released Results of Long-Term Pavement Performance SPS-3 Analysis: Preventive Maintenance of Flexible Pavements. Conclusions from this report include: Thin overlay and chip seal were more effective than slurry seal and crack seal treatments and performed better than the control section for fatigue cracking. Thin overlay mitigated and slowed the progression of rutting under all circumstances. Thin overlays outperformed the other treatments followed by chip seals for any existing level of rutting. Thin overlays and chip seals outperformed other treatments when the existing section had minimal cracking prior to the treatment and higher levels of preexisting cracking. All treatments were effective to some degree relative to the performance of the control section. View Report

 Asphalt for LEED Credit Understanding the importance of LEED credit for new development or commercial paving work is becoming more and more important. NAPA has developed a handy document to explain Asphalt Pavements and the LEED Green Building System For more info, contact Tom Clayton at tomclayton@co-asphalt.com
Concrete Industry Promotion Debunked
LEED and Green Construction - The U.S. Green Building Councils LEED (Leadership in Energy and Environmental Design) Green Building Rating System serves as a scorecard for the design, construction, and operation of green buildings. It was designed to encourage the adoption of sustainable building and development practices. Sustainable development tries to balance the needs of people, nature, and the economy. Pavement type selection (concrete vs. asphalt), on its own, directly contributes to only a few LEED credits. Credits can be earned in these ways: (read more) Thin Lift Overlays for Pavement Preservation Agencies are being forced to stretch road improvement budgets and to maximize the number of roadways being repaired and improved. Thin lift overlays are a tool in the box for pavement preservation. Best practices for material selection need to be followed when using thin lift overlays. In the Pueblo area, a new thin lift gradation (SX Modified) has been developed for 1-1/2 or less paving lifts with a 3/8 nominal maximum aggregate size (read more).
