Pavement, in construction, is an outdoor floor or superficial surface covering. Paving materials include asphalt ; concrete ; stone such as flagstone, cobblestone, and setts; artificial stone ; bricks; tiles; and sometimes wood. In landscape architecture, pavements are part of the hardscape and are used on sidewalks, road surfaces, patios, courtyards, etc.

Pavement comes from Latin pavimentum, meaning a floor beaten or rammed down, through Old French pavement. The meaning of a beaten- down floor was obsolete before the word entered English.

Pavement laid in patterns like mosaics were commonly used by the Romans.
