The construction of ultra high volume FA pavements, containing more than 90% FA, has appeal on both cost and environmental grounds. The term "pavement" is used to refer to the entire structure of the road, from foundations through to the top surface.
The major benefits demonstrated with the use of FA in pavements include:
The use of large volumes of FA in road construction helps to conserve natural resources. This reduces the environmental impact that would otherwise be caused by mining these resources.
