| abstract | - Asphalt (US /ˈæsfɔːlt/ or UK /ˈæsfælt/, occasionally /ˈæʃfɔːlt/), also known as bitumen (/bɪˈtjuːmən, baɪ-/), is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek asphaltos, which in turn was borrowed from an Eastern word. The primary use (70%) of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In American English, asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geologists often prefer the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another archaic term for asphalt/bitumen is "pitch". Naturally occurring asphalt/bitumen is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at is sometimes referred to as "refined bitumen".

* 1 (block of) Fossils from the Fossil layer with a Stone Mining Cell
* 1 Glob of Goo made from Mold in a Processor or looted/harvested from many creatures including Pigsies
* 2 pieces of Coal extracted from Coal Nodes in Mountains or on the Fossil layer underground by using any kind of Extractor, or found in Wood Treasure Chests on the surface Running across Asphalt blocks does not boost the speed of running.
