What Is Bitumen?
Bitumen is actually the liquid binder that holds asphalt together, a thick black crude oil.
Bitumen is mainly used in paving and roofing applications.
A bitumen-sealed surface is a layer of bitumen sprayed and then covered with an aggregate. This is repeated, leaving you with a two-coat seal.
Asphalt is produced by mixing aggregate, bitumen and sand into a composite.
The thick bitumen can be mixed, as a binder, with gravel and crushed rocks, then applied to roads, runways, parking lots and foot paths.
