What is Bituminous Concrete? (with pictures)

May 02, 2020 · Bituminous concrete is also known as asphalt. Bituminous concrete is a type of construction material used for paving roads, driveways, and parking lots. It's made from a blend of stone and other forms of aggregate materials joined together by a binding agent. This binding agent is called "bitumen" and is a by-product of petroleum refining.
