Registration for the FREE Two Decades of Positive Thinlay Performance at the NCAT Pavement Test Track webinar that will be conducted by Dr. R. Buzz Powell, P.E., Associate Director & Research Professor, National Center for Asphalt Technology, is now open. The webinar is scheduled for January 21, 2021, 3:00 - 4:00 PM Eastern Time (US and Canada).
The Perpetual Pavement Award is an excellent opportunity to highlight asphalt's long-life characteristics. The award honors state and local agencies that have had the foresight to design and build asphalt pavements which have long life, are cost-effective, and provide the comfort and convenience that the traveling public expects.
The APA invites you to submit an entry for the 2020 Perpetual Pavement Award. Applications will be reviewed by engineers at the National Center for Technology (NCAT). The deadline for nominations is December 1, 2020. Winners will be announced in the first quarter of 2021.
The third and final video fo the Asphalt Pavement Principles series has just been posted to FHWA's YouTube channel. Long-Life Pavements, traditionally called Perpetual Pavements, are multi-layer pavement designs built from the bottom up, with each layer engineered to maximize pavement life. Long-Life Pavement designs provide agencies with an approach that reduces the life-cycle costs of a pavement. With this approach, asphalt roads can be built with a structure that lasts many decades with only periodic surface renewal and maintenance required, making it an ideal choice for drivers, engineers, and the traveling public.
UPDATE: PerRoad is now on Version 4.4 with performance improvements and bug fixes. The Asphalt Pavement Alliance is hosting a webinar on May 30 to introduce Version 4.3 of PerRoad Perpetual Pavement design software. Developed at Auburn University, PerRoad uses the mechanistic-empirical design philosophy to estimate stresses and strains that would prove detrimental for fatigue cracking or structural rutting.
Ahead of the summer driving season, a new survey from the Asphalt Pavement Alliance (APA) finds U.S. drivers increasingly frustrated with the state of U.S. roads.
Cincinnati – The Asphalt Pavement Alliance (APA) today announced a new publication, Perpetual Asphalt Pavements: A Synthesis.
