It is widely used as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may be made from granite, limestone, dolomite, and other rocks. Also known as "crusher run", DGA (dense grade aggregate) QP (quarry process), and shoulder stone. [30] Crushed stone is distinguished from gravel by the U.S. Geological ...
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel , which is produced by natural processes of weathering and erosion and typically has a more rounded shape.
Macadam is a type of road construction pioneered by Scottish engineer John Loudon McAdam c. 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to ...
Aggregate base (AB) is typically a mix of different sizes of crushed rock 20 mm or 3 ⁄ 4 in Aggregate Base, Class 2, is used in roadways and consists of rock particles of size 20 mm (3 ⁄ 4 in) and less. An aggregate is normally made from newly quarried rock, or it is sometimes allowed to be made from recycled asphalt concrete and/or ...

The CBR is expressed as a percentage of the actual load causing the penetrations of 2.5 mm or 5.0 mm to the standard loads on crushed stone. A load penetration curve is drawn. The load values on standard crushed stones are 1,370 kgf (13.44 kN) and 2,055 kgf (20.15 kN) at 2.5 mm and 5.0 mm penetrations respectively. [citation needed]
A hollow way (chemin creux) at La Meauffe, Manche, FranceA sunken lane (also hollow way or holloway) is a road or track that is significantly lower than the land on either side, not formed by the (recent) engineering of a road cutting but possibly of much greater age.
[1] By convention in Tucson, streets run east–west while avenues run north–south. However, in a few areas of Tucson, primarily around the central part of the city, which is divided by railroad tracks running diagonally from southeast to northwest, builders created small subdivisions of roads and houses that also are laid out on a diagonal ...
