    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 con

    Limestone Aggregate in Asphaltic Concrete. Limestone aggregate is also generally suitable for use in Asphaltic Concrete and is economically feasible when the absorption is relatively low (Less than 2.5%). High absorption rates may result in added asphalt binder needed to allow for asphalt absorbed by the aggregate. However, if used in a wearing

    OverviewDescriptionClassificationFormationLimestone landscapeUsesDegradation by organismsSee also

    Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2. In old USGSpublications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomi
