請問英文 bitumen 和 asphalt 的區(qū)別 是不是bitumen是瀝青的總稱,而asphalt一般是指天然瀝青? |

http://zhidao.baidu.com/question ... asphalt%C7%F8%B1%F0 pitch 通常鋪在房頂、木板、船身上來防水; asphalt 尤其指鋪在馬路上的瀝青; bitumen (澳大利亞英語常用,非正式)指柏油路面,瀝青路面; mineral resin 一般指礦物樹脂; asphaltum 指瀝青原材料 不知是不是這樣 |

Asphalt (US Listeni/ˈæsfɔːlt/ or UK /ˈæʃfælt/),[1][2] also known as bitumen (/bɪˈtjuːmən, baɪ-/),[3][4] 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.[5] 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.[6] 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. Geological terminology often prefers the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar", such as at the La Brea Tar Pits. Another term, mostly archaic, refers to asphalt/bitumen as "pitch". The pitch used in this mixture is sometimes found in natural deposits but usually made by the distillation of crude oil. Naturally occurring asphalt/bitumen is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses[7][8] while the material obtained from the fractional distillation of crude oil [boiling at 525 °C (977 °F) is sometimes referred to as "refined bitumen". |
