Aggregate Base Course often referred simply as ABC, has certain desirable properties. Base Course in pavements refers to the sub-layer material of an asphalt roadway and is placed directly on top of the undisturbed soil (Sub-Grade) so as to provide a foundation to support the top layers of the pavement.
What is ABC stone used for?

ABC soil in American English
a vertical section of soil made up of three distinct layers: the top layer (A-horizon) is mostly humus, the middle layer (B-horizon) is of clay and oxidized material, and the bottom layer (C-horizon) consists of loose rock and other mineral materials.
