Using Aggregates in Concrete Pavement Bases and Sub …
Concrete Pavement Sub-Base. Concrete pavement sub-base is a layer that protects the soil. The layer compacts and protects the soil so that it isn't damaged. The material that is laid over the soil, and is used for the sub-base, is aggregate. The reason why pavement must have a sub-base is because a vehicle's weight needs strong support.
