Zeller has been with CPAM since 2001 and has more than 20 years of experience in the concrete paving industry. He holds responsibilities for running the day-to-day operations, directing promotional efforts and working with MnDOT to develop policies in support of quality concrete pavement.
Government Official of the Year
This year, Tom Yager, distinguished research associate at the NASA Langley Research Center, has been selected to receive the Government Official of the Year Award for his decades of commitment towards the efforts to improve aircraft ground handling performance in adverse weather, specifically with diamond grooved pavement surfaces. The Government/Public Official of the Year Award recognizes leadership in transportation activities with special emphasis on grooving, grinding and CPR.
In 1963, Yager began his career with NASA Langley Research Center in the Structural Dynamics Branch, where he now serves as a distinguished research associate. In his role, he has been involved with several multi-agency/organization programs evaluating aircraft ground handling performance. Yager earned his Bachelor of Science in engineering science from the University of Portland, Ore. He has authored and/or co-authored more than 130 technical reports, journal articles and conference/workshop papers documenting NASA career activities and accomplishments. Further, Yager has been recognized for several industry awards such as the NASA Exception Engineering Achievement Medal in 1990 and 1997 and the Space Technology Hall of Fame Award for Safety Grooving in 1990. Yager's instrumental work has paved the way for several organizations to enlist his help and knowledge including the National Transportation Safety Board, Federal Aviation Administration, Federal Highway Administration, Transport Canada, International American Society for Testing and Materials, Society for Automotive Engineering, Transportation Research Board and the International Civil Aviation Organization.
“Recognition by the IGGA for my work promoting pavement grooving and grinding is an honor to me,” said Yager. ”I started doing NASA research on grooved pavements in 1964 here at Langley. Back then, we were interested in minimizing tire hydroplaning only on wet runways during aircraft landing and aborted takeoff operations. From here, this technology spun-off to highways and walkways. I understand that currently, in just the U.S., there are nearly 1,000 runways with transverse grooving installed to improve aircraft wet pavement braking performance.”
