Burt Morey is the Deputy Secretary and State Transportation Engineer at the Kansas Department of Transportation. He has filled this role since February 2019.
Upon graduation from Kansas State University with a B.S. in Civil Engineering, Burt began a career in transportation engineering. He has worked in this field for 30 years. In that time, he has worked for various local government and the private sector in bridge design, construction engineering and contract administration. He served as the KDOT Metro Engineer in Johnson County from 2007 to 2012. In 2012, Burt was selected to be the Project Director for the Johnson County Gateway design-build project -- KDOT’s first design-build and largest project at the time. From November 2015 through February 2019, he served as the City Engineer of Overland Park, Kansas.
Burt and his wife Jan live in rural Leavenworth County, they have two adult children and two German Shorthaired Pointers.
Originally from Canada he joined Saskatchewan Highways and Transportation where he worked for 10 years.
He joined the Asphalt Institute research center in Lexington, Kentucky. Was involved in the Strategic Highway Research Program (SHRP) working on the team responsible for developing Superpave.
Gerry now works as research engineer based in Indianapolis, Indiana for the Heritage Research Group, the research arm of companies involved in the asphalt industry.
Over the years he has been involved in Expert Task Groups for asphalt binder and for asphalt mixture. He is currently involved in the FHWA Technical Working Group on Pavement Sustainability.
His interest in what is now called Superpave5 started in the 1990s from visits made to the Central Laboratory of France
Increasing In-Place Density With No Change in Material or Construction Cost
The relationship between laboratory compaction (design) and field compaction was set when the Marshall mix design system was developed in the 1940s. Air voids in the lab (design) were set between 3 to 5 percent. Air voids in the field were about 8% (96% of Marshall density). Superpave mix design, developed in the 1990s used this same relationship.
In 2010 Superpave5 research work began. Superpave5 is similar to Superpave except design air voids are set at 5 percent and compaction on the road is targeted to be 5 percent. Laboratory compactive effort for Superpave5 is 50 gyrations for most mixtures (greater than 3 million ESALs) and 30 gyrations for less than 3 million. The first Superpave5 project was constructed in 2013 and in 2019 the Indiana Department of Transportation began transitioning to Superpave5 based on the five-year performance. In 2020 the transition was complete and all mixtures supplied since 2020 have been based on Superpave5 mix designs.
This presentation will discuss research done to develop Superpave5, and the effect that Superpave5 has on the design method, material selection, and construction. Acceptance specifications and performance observations will also be discussed.
Greg has worked at KDOT for 21 years since graduating from the University of Kansas. He is currently the Director of Project Delivery which is responsible for the construction administration and materials acceptance of KDOT’s construction contracts from Letting through Acceptance and KDOT’s Research programs. Also, the Division manages KDOT’s Pavement Preservation Program.
Optimization of HMA Thickness for Full Depth Reclamation Projects
KDOT in partnership with K-State University has completed a research project that evaluated the mix design for Full Depth Reclamation. A test pit was constructed at the Civil Infrastructure System Laboratory at KSU to evaluate and optimize the HMA thickness over Full Depth Reclamation.
1.) Where KDOT would scope a Full Depth Reclamation project.
2.) Critical Mix Design properties for Full Depth Reclamation.
3.) What HMA thickness to place over Full Depth Reclamation for various traffic levels.
Vice President of Customer Success IPS group – Astec Industries
Greg Renegar joined Astec in 1985 after graduating from the University of Tennessee at Chattanooga with a Bachelor of Science in Mechanical Engineering. Since joining Astec, Greg has worked in North America, South and Central America, Asia, Australia, and throughout Europe as a field engineer, project engineer, and speaker. Greg previously help positions as Director of Thermal Systems, Chief Engineer, VP of Engineering (asphalt plant division), and VP of Engineering for the Astec IPS group. Greg became president of Astec Inc. (asphalt plant division) in 2019, and is currently the VP of Customer Success for the Astec Industries IPS group.
