ii Abstract: Cementtreated base (CTB) is a mixedinplace or centralplantproduced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.
