DADO: Concrete barrier on the sides of bridge approach slab; the part of pedestal between cap and base.
DATUM: Any elevation taken as a reference point for leveling.
DECK: (1) A flat roof, a quay, jetty or bridge floor, generally a floor form with no roof over upon which concrete for a slab is placed. (2) Formwork for a level surfaces.
DEFORMED BAR: A reinforcing bar with ridges to increase bonding between the reinforcing bar and concrete.
DENSITY INDEX (relative density): is a measure of the tendency or ability to compact soil during loading. The density index is equal to 1 for a very dense soil; it is equal to 0 for a very loose soil.
DETOUR: A temporary route for traffic around a closed portion of a road.
DEVIATION: Difference between the value and the average of a set.
DIAPHRAGM: (1) A stiffening plate in a bridge between the main girders in a bridge or a stiffening web across a hollow building block. (2) Legamentous wall separating two cavities.
DILUTION: Reducing a concentration of soluble material by adding pure water.
DISTILLATION: Salt removal process from brackish or sea water by boiling and condensation.
DITCH: Long narrow excavation for drainage, irrigation or burying underground pipelines.
DIVIDED HIGHWAY: A highway with separated traveled ways for traffic, generally in opposite directions.
DREDGE: To dig or excavate under water.
DUCT: A protective tube or a brick or concrete trench or corridor along which pipes or cables pass through the ground.
DUCTILITY: The ability of a metal to undergo cold plastic deformation without breaking, particularly by pulling in cold drawing.
DURABILITY: The ability of materials to resist weathering action, chemical attack, abrasion or other conditions of service.
DYKE: (1) A mound of earth along a river or channel bank to retain floodwater. (2) large ditch. (3) A tabular-shaped igneous intrusion.
