Pavage

Pavage is the process of covering a surface with a durable, uninterrupted layer of hard material, typically for purposes of travel, foot traffic, or load-bearing use. It encompasses a wide range of materials, layouts, and installation methods used in streets, sidewalks, courtyards, and plazas. The term derives from the French pave, meaning to cover with paving.

Common pavage materials include natural stone setts and flags, brick, concrete pavers, and asphalt. Stone pavements may use dressed flagstone, granite setts, or cobbles arranged in patterns such as running bond, herringbone, basket weave, or random ashlar. Permeable pavement systems use porous aggregates or modular pavers to allow infiltration of rainwater.

Installation practices vary: dry-laid systems rely on a compacted sub-base and bedding sand, with joints filled by sand or resin; mortared systems use a bed of mortar and often setting beds; jointing materials help lock units in place. Slope and drainage, frost action, and load expectations influence material choice and joint width. Maintenance may include cleaning, sealing, and periodic replacement of damaged units.

Historically, pavings appear in ancient civilizations with road paving in Roman times; medieval towns used stone slabs and cobbles; in the 18th–19th centuries cities widely adopted stone pavements; 20th century saw asphalt and concrete pavements become standard for roads; in recent decades, modular concrete or clay brick pavers and permeable systems have been used for ease of replacement and environmental considerations.

Today, pavage design considers accessibility, drainage, durability, and lifecycle costs. Permeable pavements help reduce runoff and recharge groundwater, while decorative patterns and colors enable urban design aesthetics. The field overlaps with civil engineering, landscape architecture, and historic preservation.
