There is none. Bitumen is not a pure compound but a very complex mixture of various large, branched, (poly)aromatic or olefinic hydrocarbon polymeres.
Bitumen is a mixture of many organic compounds, not only one chemical compound.
Bitumen (asphalt) (tar) is a mixture of chemicals left over at the end of a distillation process. As it is not a pure substance (a single chemical), we cannot provide you with a chemical formula.
Perhaps the main effect on the physical apperance of bitumen caused by aging is stiffening; the bitumen gets less fluid. This applies to pure bitumens without modification. Indeed, bitumen aging is complex both in chemical and physical terms.
why bitumen is used
Mustek manufactures a variety of packed bitumen products. Their bitumen products are produced at the Europoort refinery in Rotterdam, Germany. They produce 3 types of bitumen: penetration bitumen,oxidized bitumen, and hard bitumen.
Bitumen is use as fuel.
Typically, bitumen and "asphalt" are interchangeable.

Petroleum bitumen is often confused with tar. Although bitumen and coal tar are similarly black and sticky, they are distinctly different substances in origin, chemical composition and in their properties. Coal tar is produced by heating coal to extremely high temperatures and is a by-product of gas and coke production. It was widely used as the binding agent in road asphalt in the early part of the last century, but has since been replaced by refined bitumen.
'asphalt' refers to a mixture of mineral aggregate and bitumen (bitumen)is the black liquid which is extracted from the crude oil....
