asphalt and mineral aggregate and a base course. The base course is generally com­ posed of granular material such as crushed aggregate, gravel, selected soil, or a mix­ ture of selected soil and aggregate. Since the cost of the surface course per ton is sev­ eral times that of the base course, its thickness is generally just a fraction of ...

Pavement materials: Aggregates

RYAN Aggregate is a collective term for the mineral materials such as sand, gravel, and crushed stone that are used with a binding medium (such as water, bitumen, Portland cement, lime, etc.) to form compound materials (such as bituminous concrete and Portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of ...

Aggregate Base Courses - Buildipedia

2009-8-14  An aggregate base course is the layer of soil installed between the surface pavement layer and subgrade (foundation soils) of either flexible or rigid pavement.Their purpose is to help transition surface loads from the pavement to the subgrade, evenly support the pavement surface profile, and protect the overall pavement system from water intrusion and deformation.
