Portland Cement Association. 5420 Old Orchard Road Skokie, Illinois 60077-1083 847.966.6200 Fax 847.966.9781 Abstract: Cement-treated base (CTB) is a mixed-in-place or central-plant-produced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
SC for pavements, water resources, and geotechnical projects can be either mixed in place or in a central mixing plant close to the project site. Central mixing plants can be used where borrow material or blends of material are involved. Friable granular materials are selected for their low cement requirements and ease of handling and mixing.
