Warm-Mix Asphalt Wins NOVA Award
The National Asphalt Pavement Association (NAPA) has received the prestigious 2013 NOVA Award from the Construction Innovation Forum (CIF) for its work to speed the deployment and uptake of warm-mix asphalt.
"NAPA is proud to accept this award on behalf of the asphalt pavement industry, warm-mix technology developers, and our partners at the Federal Highway Administration (FHWA) and state departments of transportation nationwide. The success of warm mix is due to cooperation and a willingness to innovate from road owners and builders alike," said NAPA President Mike Acott.
In selecting warm mix to win a 2013 NOVA Award, the investigators cited its ability to improve compaction, reduce fuel or energy use, improve worker comfort, lengthen the paving season, and reduce overall paving costs. Continued
Research Finds Unintended Consequences of Reflective Pavements
Addressing the urban heat island effect (UHI) is a growing concern for many municipalities, but a new report from Arizona State University (ASU), "Unintended Consequences: A Research Synthesis Examining the Use of Reflective Pavements to Mitigate the Urban Heat Island Effect," calls into question many common assumptions about the ability of reflective pavements to mitigate UHI.
Reflective surfaces redirect solar energy and for this reason high-albedo, reflective, or "cool" roofs have been suggested as an important tool for UHI mitigation. However, efforts to apply the same principle to pavements overlook the complexities of urban geography and how ground-level reflections interact with pedestrians, vehicles, and the built environment.
"We cannot assume that reflective pavements will behave the same as reflective roofs. When energy is reflected from a ground surface, it doesn't return directly to the sky. It reflects back at buildings and pedestrians. Heat concentration in urban areas is a multifaceted problem; it requires a solution that looks at more than just one mitigation strategy," said Heather Dylla, Ph.D., Director of Sustainable Engineering for the National Asphalt Association (NAPA).

Sen. Boxer Honored for Her Leadership on MAP-21
The National Asphalt Pavement Association (NAPA) today (Sept. 11, 2013) presented Sen. Barbara Boxer (D-Calif.) with the Asphalt Legislator of the Year Award for her bipartisan leadership in crafting the Moving Ahead for Progress in the 21st Century Act (MAP-21).
"We commend Senator Boxer for her extraordinary leadership in advancing legislation that will truly modernize and reform the nation's current transportation system to help create jobs, accelerate economic recovery and build the foundation for long-term prosperity,” said John Keating, President and COO East of Oldcastle Materials Inc. and Chairman of the Board of Directors for NAPA.
Boxer is being recognized for her single-minded pursuit of a bill to reauthorize the surface transportation programs. She ignored naysayers who said a bill would never pass. She overcame objections from stakeholders opposed to certain compromises. She stuck to a bipartisan path, and had the courage to set aside policy goals that were near and dear to her. Despite the bitter partisan division in Congress and the many distractions of a presidential campaign year, Boxer succeeded.... continue
