Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.

Coarse and fine aggregates, suitable for use in bituminous paving mixtures, consist of hard, tough, durable natural river rocks shall be processed, by crushing, screening, and washing into S1, 3/4, 3/8, and G1. At the time of delivery, the aggregates shall not contain injurious amounts of foreign materials such as clay, loam, wood, metallic contents, unhydrated lime, or other deleterious materials. The physical requirements conform to are grading and fineness modulus, soundness, degradation, expansion, friable particles, stripping, adherent coatings, crushed count, and environmental stability. American Society for Testing and Materials (ASTM) Free from adherent coatings, organic matter etc. and shall not contain any appreciable amount of clay balls or pellets and harmful impurities e.g. iron pyrites, alkalies, salts, coal, mica, shale or similar laminated materials in such form or in such quantities as to cause corrosion of metal or affect adversely the strength, the durability or the appearance of mortar, plaster or concrete.
