"Aggregate" is a collective term for sand, gravel and crushed stone mineral materials in their natural or processed state (NSSGA, 1991). In 2000, the U.S. produced over 3 billion tons of aggregate at a value of about $14.2 billion.

• Cement-treated base. Sizes and Designations Sizes and designations vary by location due to governing agency requirements. Common designations include, but are not limited to: Base, Subbase, Dense Graded Base, Crushed Stone Base, Graded Aggregate Base (GAB), Aggregate Base Course (ABC), Macadam Base Course (MBC)
Traditionally, base course aggregate mixtures have been designed using larger aggregate size than surface course aggregate mixtures—the maximum aggregate size had tended to be in the range 0.75–1.5 inches (19–37.5 mm) which helps to produce a lean mixture with low asphalt binder content thereby reducing the cost of such mixtures but this ...
Aggregate Baserock Primer. Aggregate Baserock is a dense graded blend of coarse and fine aggregate which when properly placed and compacted provide a stable and durable base allowing further construction. Aggregate Baserock Should Demonstrate: Stability: Resist deformation when under load (after proper placement and compaction).

Aggregate base is a construction aggregate typically composed of crushed rock capable of passing through a 20 millimetres (3 ⁄ 4 in) rock screen.The component particles will vary in size from 20 mm down to dust. The material can be made of (newly mined) rock, or of recycled asphalt and concrete.
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.

Dense-graded base course are aggregates having different particular size. Recycled aggregates in concrete can also be of use. They form a dense layer having stones ...
subgrade (Figure 5). The base layer is typically provided to support construction traffic and to provide uniformity of support to the PCC surface. The base layer may consist of unbound aggregate, bitumen-, or cement-bound aggregate. The bound layers may be conventional dense-graded asphalt, lean concrete, or cement-treated; or open-graded
