Michigan installs first recycled tire chip seal application in the United States
“The work in Kalamazoo demonstrated new applications,” Michigan Technological University professor of civil and environmental engineering Zhanping You says. “Ground tire rubber (GTR) has generally not been used much in chip seals and the products that are being used for this project are being used for the first time used in the U.S.”
“The project included reacted rubber for both the hot rubber chip seal (HRCS) and the hot rubber thin overlay (HRTO) based on the research development,” You says. “Michigan Tech researchers have used GTR in asphalt emulsion so that the GTR modified asphalt emulsion is used for a different rubber chip seal, which is very different than the HRCS.
