The mineral commonly used in the construction of roads is limestone. Limestone is a sedimentary rock composed mainly of calcium carbonate. It is often crushed and used as an aggregate material for road construction, providing stability and strength to the roadbed. In addition to being a strong base material, limestone is also readily available and affordable, making it a popular choice in construction. Its durability under traffic loads and resistance to wear further enhance its suitability for road application, contributing to the infrastructure of highways, streets, and various transportation networks.
