济南沥青材料是一些极其复杂的高分子碳氢化合物与其他非金属(氧、硫、氮)衍生物所组成的混合物，其中碳占80％一87％，氢占10％～15％，氧、硫、氮小于0．3％，此外还有少量微量金属元素。石油沥青化学组分按四组分法可分为饱和分、芳香分、胶质和沥青质。

Asphalt material is a mixture of highly complex polymer hydrocarbons and other non-metallic (oxygen, sulfur, nitrogen) derivatives, with carbon accounting for 80% to 87%, hydrogen accounting for 10% to 15%, oxygen, sulfur, nitrogen less than 0.3%, and a small amount of trace metal elements. The chemical components of petroleum asphalt can be divided into saturated fraction, aromatic fraction, resin, and asphaltene according to the four component method.

济南沥青按其在自然界中获得的方式，可分为地沥青和焦油沥青两大类。

Asphalt can be divided into two categories based on the way it is obtained in nature: ground asphalt and tar asphalt.

地沥青按其产源又可分为天然沥青和石油沥青。天然沥青是石油在自然条件下，长时间经受地球物理因素作用而形成的产物：石油沥青是石油经精制加工成油品后，最后加工而得到的产品，现用于公路沥青路面。

Asphalt can be divided into natural asphalt and petroleum asphalt according to its source of production. Natural asphalt is a product formed by petroleum under natural conditions and long-term exposure to geophysical factors: petroleum asphalt is a product obtained by refining petroleum into oil products and finally processing it, and is now used for highway asphalt pavement.

焦油沥青是各种有机物(煤、泥炭、木材等)干馏加工得到的焦油，经再加工而得到的半成品，我国常用的焦油沥青是煤沥青。

Tar pitch is a semi-finished product obtained by the dry distillation and processing of various organic substances (coal, peat, wood, etc.), and further processed. The commonly used tar pitch in China is coal tar pitch.

目前，我国在炼油厂中生产沥青的主要工艺方法有：蒸馏法、氧化法、半氧化法、溶剂脱沥青法和调配法等，由于制造方法不同，沥青性质有很大差异。

At present, the main process methods for producing asphalt in refineries in China include distillation, oxidation, semi oxidation, solvent deasphalting, and blending. Due to different manufacturing methods, the properties of asphalt vary greatly.
