下面以某济南沥青生产厂家为例，介绍公路沥青的生产工艺流程。首先，通过精炼、分离等一系列工艺处理得到原沥青。原沥青主要成分为碳氢化合物，与水不溶，比重大于1，黏度大，黑色或暗褐色半固体或膏状物。然后，在沥青罐区进一步加工原沥青，去除杂质，通过加热、混合等处理，使其变成适合于公路铺设的沥青材料。具体工艺流程如下:

The following with some Jinan bitumen manufacturer for example, introduce the production process of highway bitumen. First, the raw bitumen is processed through a series of processes such as refining and separation. Raw bitumen is mainly composed of hydrocarbons, insoluble with water, with a weight greater than 1, a high viscosity, a black or dark brown semi-solid or paste. Then, in the bitumen area, the raw bitumen is further processed, impurities are removed, and it is turned into a bitumen material suitable for road laying through heating, mixing and other treatments. The specific process is as follows:

一、混合

将原沥青、多级渣油、催化油加入沥青混合罐中，进行搅拌，调整沥青质量，保证产品的稳定性和合格率。

1. Mixing

The original asphalt, multigrade residue and catalytic oil were added into the asphaltmixing tank, and the asphalt quality was adjusted to ensure the stability and qualified rate ofthe product.

二、加热

将混合后的沥青逐步加热，通过蒸汽加热管和回流器对沥青进行均匀高效的加热，使其成为适于运输、铺设的黏稠液态。

ll. Heating

The mixed asphalt is heated step by step, and the asphalt is uriformly heated through a steam heating pipe and a refiuc device.

Efficient heating makes it a viscous liquid suitable for transportation and laying.

三、过滤

沥青材料在混合和加热的过程中，可能会产生小颗粒的杂质。因此，必须通过过滤去除杂质。在这一流程中，常用多级过滤器，以准确滤出所需要的颗粒，而不会过滤掉沥青中的有用成分。

lll.Filtering

In the process of mixing and heating asphalt materials, small particles ofimpurities may be produced.Therefore, impurities must be removed by filtration.In this process, a multi-stage filter is used to accurately filter out the desiredparticles without filtering out the useful components in the asphalt.

四、储存

经过加工后的沥青需要进行储存，储存过程中需要保证沥青的稳定性质量和纯洁度。为了达到这个目的，通常采用封闭罐体进行储存。

IV. STORAGE

After processing asphalt needs to be stored, the storage process needs to ensure the stability of asphaltQuality and purity, For this purpose, dosed tanks are usually used for storage.

以上就是公路沥青生产工艺的流程，每个工序都需要注意质量和安全。

The above is the process of highway asphalt production, and each process needs to pay attention to quality and safety.
