Pavement systems containing cement-bound layers have been used worldwide for over a century, with great success. Portland cement can be used in virtually every layer in a pavement system. Typical applications include improving the quality of subgrade soils and stabilizing base materials. Integrating multiple cement-based layers into a pavement design may provide a cost-effective method for achieving a stronger, more durable, sustainable pavement.
