Construction aggregate - Wikipedia

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 co

PROPERTIES AND TESTING OF AGGREGATES FOR PAVEMENT WORKS

Aggregates plays vital role in the construction of pavement. They have great capability of load transfer to the Subgrade soil. Aggregates have different properties which are tested individually with different types of tests for the construction of pavement.
