The performance of a section of concrete pavement built with 30 percent Ground Granulated Blast Furnace Slag (GGBFS) is compared to a control section of concrete pavement built with 25 percent GGBFS to determine if the higher slag content pavement is more resistant to wear from studded tires. The wear measurements made over a period of six years showed minimal amount of wear on both the higher slag content section and the control section. It was impossible to conclude that the higher slag content was more resistant to studded tire wear than conventional concrete mixes normally used on Washington roadways. The low speed of vehicles (40 mph speed limit) is a possible contributing factor to the lower amounts of wear noted on this project.
