Bitumen is a mixture of many organic compounds, not only one chemical compound.
That's correct—bitumen doesn't have a single chemical formula because it's a complex mixture of high-molecular-weight hydrocarbons, along with small amounts of sulfur, nitrogen, oxygen, and trace metals. Its exact composition varies depending on the crude oil source and refining process. If anyone needs a deeper explanation of bitumen's composition, properties, or practical calculations (such as estimating bitumen quantity for paving projects), I recently found a detailed resource that explains these topics clearly: BitumenCalcPro. It may be useful if you're looking for more technical information or calculation examples.
Typically, bitumen and "asphalt" are interchangeable.
There is none. Bitumen is not a pure compound but a very complex mixture of various large, branched, (poly)aromatic or olefinic hydrocarbon polymeres.
The thinner commonly used for bitumen is called mineral spirits. It is a petroleum-derived solvent that helps in thinning bitumen for various applications, such as painting, sealing, or coating.

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 mainly used as a binding and waterproofing material, not as a fuel. It is widely used in road construction, roofing, bridge decks, airport runways, and pavement maintenance because it provides durability, flexibility, and resistance to water. While some heavy petroleum residues may be used as fuel in specific industrial applications, the primary use of bitumen is in infrastructure and construction. If you're trying to estimate how much bitumen is needed for a paving project, a bitumen calculator can make the calculations much easier. I’ve found BitumenCalcPro to be a useful free tool for estimating bitumen quantity, mix weight, and project costs.
