Process In Construction Aggregate Base Course

Aggregate Base Course vs. Crushed Concrete Aggregate

Aggregate base course is typically installed and compacted, thus providing the stable foundation that’s needed to support either additional layers of aggregates or the installation of the wearing course (which is constructed directly on top of the base course).

Base course Wikipedia

The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field.It is located under the surface layer consisting of the wearing course and sometimes an extra binder course.. If there is a sub-base course, the base course is constructed directly above this layer.
