Peter Taylor, civil, construction and environmental engineering research associate professor and associate director of the National Concrete Pavement Technology Center, led a general session keynote speech Feb. 5 at Iowa Concrete Pavement Association’s (ICPA) 51st Annual Concrete Paving Workshop. The ICPA Workshop was held at The Meadows Events and Conference Center in Altoona, Iowa.
Taylor, with Leif Wathne, head of Highways and Federal Affairs for the American Concrete Pavement Association, discussed the latest engineering technologies pertaining to concrete pavements. One technology is mixing limestone with fly ash, which reduces carbon dioxide footprint and increases pavement strength and durability. Other technologies include smog-reducing titanium oxide, ice-free surfaces, pavement recycling, and more.
In a later workshop session, Taylor discussed performance engineered concrete mixtures. He proposed a mixture proportioning procedure that prescribes aggregate, paste volume and paste strength within a cement mixture.
ICPA’s Annual Concrete Paving Workshop invites highway officials, engineers, contractors, and paving experts in Iowa to promote a nationally recognized paving industry/ready-mixed concrete industry. In addition to technical discussions, several Iowa concrete professionals and students are honored.
