  • What are Different Layers in a Bituminous Pavement?

    Different Layers in a Bituminous Pavement 1. Bituminous Base Course. Base course layer in a bituminous pavement consists of mineral aggregates such as gravel, stones and sands bonded together with bituminous materials. This layer is used as the foundation on which surface course or binder is placed.

    What is Bituminous Concrete? with pictures

    Bituminous concrete is a type of construction material used for paving roads, driveways, and parking lots. It& 39;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. It has a thick, sticky texture like tar when heated, then forms a dense solid surface once it dries ...

    What is the significance of bleeding in bituminous pavement?

    Bleeding occurs in bituminous pavement when a film of asphalt binder appears on road surface. Insufficient air void is a cause of bleeding in which there is insufficient room for asphalt to expand in hot weather and it forces its way to expand to pavement surface. Too much asphalt binder in bituminous material is also a common cause of bleeding. Bleeding is an irreversible process the bleeded ...
