Precast concrete products were on the agenda of the 99th annual Transportation Research Board meeting in January in Washington, D.C. Over 12,000 delegates heard presentations in 800-plus sessions addressing multimodal transportation policy and construction practice, including materials and design involving precast/prestressed products. Concrete Products was there and we present this report on new research in precast structures and methods. We will look at TRB 2019 research in cast-in-place concrete later this year. The 100th meeting of TRB will take place January 12-16, 2020. For more information, visit www.trb.org.
