Rubble is a coarse aggregate material made up of broken stones, typically sourced from quarries or demolition sites. It is commonly used as a base layer in road construction, foundation filling, and drainage applications due to its excellent load-bearing capacity and permeability. Rubble provides a strong and stable foundation for roads, buildings, and other heavy-duty structures, helping to evenly distribute weight and reduce settlement over time.

The material is cost-effective, durable, and readily available, making it a practical choice for large-scale infrastructure and civil engineering projects.
