Asphalt, also known as bitumen (uk: / ˈ b ɪ tj ʊ m ɪ n /, us: / b ɪ ˈ tj uː m ə n, b aɪ-/), is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch.
It is detailed information that defines the product and geometry that represents the product’s physical characteristics. The visualisation data that gives the object a recognizable appearance and behavioural data, such as detection zones, enables the object to be positioned or to behave in exactly the same way as the product itself.

The asphalt exhibited the following physical properties: penetration of as temperature increases, asphalt cement changes from solid to liquid, and the stiffness.
Asphalt is a black-to-dark-brown, solid or semisolid material mostly composed of bitumens. The emulsion, a suspension of fine asphalt particles dispersed in water, has little or no preservative value. This preservative contains arsenic acid, sodium arsenate, sodium bichromate, and zinc sulfate in a water solution.

• volume 103 (october 2011): bitumens and bitumen emissions, and some n- and s-heterocyclic polycyclic aromatic hydrocarbons (iarc, 2013a). • volume 105 (june 2012): diesel and gasoline engine exhausts and some nitroarenes (iarc, 2013b).
Surprising that bitumens of identical classes can have different chemical compositions as illustrated in table 2 (21) for bitumens with a 58-28 grade (29). For this reason, it is difficult to predict the stability or the reactivity of an additive in a mixture with bitumen.
Chemically, the relation between solid asphaltenes and liquid maltenes in the bitumen shifts towards a higher maltene content.
Sulfate attack of concrete is a complex process, which includes physical salt attack due to salt crystallization and chemical sulfate attack by sulfates from soil, groundwater, or seawater. Sulfate attack can lead to expansion, cracking, strength loss, and disintegration of the concrete.
