aggregate used in indian roads

Aggregates Used in Building Roadways

Aggregates are among the most used, apart from gravel, and can be used in building roads and in other concrete forms. Aggregate production is a significant part of the asphalt industry because asphalt and aggregates are mixed to pave the country’s roadways. The materials used in these aggregates include gravel, sand, and crushed rock.

Uses of Aggregates in Construction, Roads,

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
