Asphalt 和 Bitumen 都指沥青。但是,在常规使用中,asphalt 常指沥青混凝土( asphalt concrete )。此外,还有tarmac (tarmacadam的简称)在英国也常指沥青混凝土( asphalt concrete )。------from "Difference Between Tarmac Asphalt and Bitumen" by Difference Between.以下为参考原文:Asphalt and bitumen both refer to the same black, sticky semi solid or a liquid substance derived from crude oil. However, in regular use, asphalt can also be used as a shortened term for asphalt concrete which is a popular construction composite made up of bitumen and mineral aggregates. Although in UK, tarmac is a word commonly used for asphalt concrete, tarmac is a separate method in itself which involved stabilise macadam roads with tar.
