Average Daily Traffic (ADT) is the number of vehicles that pass over a roadway on an average day. Usually calculated by counting the number of vehicles that pass over a roadway for a longer period of time, such as a year, and then dividing by the number of days in that period. For this reason, ADT is also often referred to as Average Annual Daily Traffic (AADT).

Bleeding is a film of bituminous material on the pavement surface that creates a reflecting surface that becomes sticky. Bleeding is caused by excessive asphalt cement or tars in the mix, excess application of a bituminous sealant, and/or low air void content. It occurs when asphalt fills the voids of the mix during hot weather and then expands onto the pavement surface. Since the bleeding process is not reversible during cold weather, asphalt or tar accumulates on the surface.
Block cracks are interconnected cracks that divide the pavement into rectangular shaped pieces. Block cracking is caused mainly by shrinkage of the asphalt concrete and daily temperature cycling (which results in daily stress/strain cycling). It is not load-associated.
Blowups or buckles occur in hot weather, usually at a transverse crack or joint not wide enough to permit slab expansion. The insufficient width is caused by infiltration of incompressible materials into the joint space. When expansion cannot relieve enough pressure, a localized upward movement of the slab edges (buckling) or shattering occurs in the vicinity of the joint. Blowups also occur at utility cuts and drainage inlets.
Bumps are small, localized, upward displacements of the pavement surface. They are different from shoves in that shoves are caused by unstable pavement. Bumps can be caused by several factors including; Buckling or bulging of underlying PCC slabs in AC overlay over PCC pavement Frost heave (ice, lens growth) Infiltrations, and buildup of material in a crack in combination with traffic loading (sometimes called "tenting").

The difference between a corner break and corner spall is the crack extends vertically through the entire slab thickness, whereas a corner spall intersects the joint at an angle. Load repetition combined with loss of support and curling stresses usually cause corner breaks.
Corrugation (also known as washboarding) is a series of closely spaced ridges and valleys, or ripples, occurring at fairly regular intervals along the pavement. The ridges are perpendicular to the traffic direction. This type of distress is usually caused by traffic action combined with an unstable pavement surface or base. If bumps occur in a series of less than 10 ft. (3 m) due to any cause, the distress is considered corrugation.

Depressions cause some roughness, and when deep enough or filled with water, hydroplaning.

(Esri) In a database, the set of allowed values for a table column, for example all positive integers, or valid dates. Domains are often related to Cartegraph lookup fields.
"D" cracking is caused by freeze-thaw expansions of the large aggregate which gradually break down the concrete. This distress usually appears as a pattern of cracks running parallel and close to a joint or linear crack. Since the concrete becomes saturated near joints and cracks, a dark-colored deposit can usually be found around fine "D" cracks. This type of distress may eventually lead to disintegration of the entire slab.
Edge cracks are parallel to and usually within 1 ft. to 2 ft. (0.3 to 0.6 m) of the outer edge of the pavement. This distress is accelerated by traffic loading and can be caused by a frost-weakened base of subgrade near the edge of the pavement.
(Esri) A vector object is made up of three different types of elements: 1) points, which are single coordinate pairs (or triplets) that define a point (such as a well); 2) lines, which are curvilinear strings of coordinates which define a curved line (such as a stream) and which have nodes at the ends and intersections of lines; and, 3) polygons, which are collections of lines which inscribe an area (such as a lake).

This distress occurs only on asphalt-surfaced pavements that have been laid over a PCC slab. It does not include reflection cracks from any other type of base . These cracks are caused by thermal- or moisture-induced movement of the PCC slab beneath the AC surface. This distress is not load-related, however, traffic loading may cause a breakdown of the AC surface near the crack.
Any condition that enables soil or rocks to accumulate in the joints or allows significant water infiltration.

Medium- or high-severity cracks are usually working cracks and are considered major structural distresses.

Scaling may also be caused by deicing salts, improper construction, freeze-thaw cycles, and poor aggregate. The type of scaling defined here is not caused by "D" cracking. If scaling is caused by "D" cracking, it should be counted under that distress only.
