Pervious Concrete: From Missouri to the Moon!

Time: Noon – 1:00 pm CDT
Presenter: Dr. John Kevern, UMKC

Description: Pervious concrete represents one of only a few viable permeable pavement options for managing urban stormwater runoff. Pervious concrete has the ability for both stormwater volume reduction and stormwater quality improvements amongst a wide variety of other benefits such as reduction in the urban heat island and reduced risk of slip and fall. These benefits are not without significant challenges throughout the design, construction, and maintenance lifecycle, leading many to shy away in favor of more conventional stormwater management techniques. With significant green infrastructure investment on the horizon, pervious concrete will once again see a significant increase in demand and opportunity to learn from past experiences. This presentation will overview the current state of pervious concrete from site design, mixture proportioning, and placement perspectives. ACI 522, Pervious Concrete, is finalizing a complete revision of the R document and this presentation will reinforce best practices, highlight significant changes to the document all with an eye to the future. Along the way we will discuss how the pervious concrete mixture proportioning process can be applied across a variety of scales, including microporous pervious concrete produced for NASA’s Jet Propulsion Laboratory to simulate the surface of Enceladus.

Speaker Bio:  Dr. Kevern is a Professor of Civil Engineering and Chair of the Department of Civil & Mechanical Engineering at the University of Missouri-Kansas City, on the executive cabinet for the Missouri Center for Transportation Innovation (MCTI), and interim director for the Center for Urban Stormwater Research (CUSR). He is an internationally recognized expert on pervious concrete, concrete durability, and non-traditional concrete applications. He received his Ph.D. from Iowa State University. Dr. Kevern has been named one of the top five most influential people in the concrete industry by concrete construction magazine for his work with pervious concrete and is a Fellow of ACI. He chairs AKM50 Advanced Concrete Materials and Characterization committee at the National Transportation Research Board and is secretary of ACI committee 522 on pervious concrete, and founding member of ASTM committee 09.49 on pervious concrete. Some of his current research topics include improving water quality using cement-based filters, improving concrete lifespan using hydrophobic coatings, internal curing concrete, techniques to reduce cost and improve performance of soil structures in sub-Saharan Africa, and eliminating joints in concrete pavements. He has authored over 125 journal articles, papers, and reports and has been an invited presenter over 180 times at US and international conferences.
