下面以某濟南瀝青生產廠家為例，介紹公路瀝青的生產工藝流程。首先，通過精煉、分離等一系列工藝處理得到原瀝青。原瀝青主要成分為碳氫化合物，與水不溶，比重大于1，黏度大，黑色或暗褐色半固體或膏狀物。然后，在瀝青罐區進一步加工原瀝青，去除雜質，通過加熱、混合等處理，使其變成適合于公路鋪設的瀝青材料。具體工藝流程如下:

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

將原瀝青、多級渣油、催化油加入瀝青混合罐中，進行攪拌，調整瀝青質量，保證產品的穩定性和合格率。

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、加熱

將混合后的瀝青逐步加熱，通過蒸汽加熱管和回流器對瀝青進行均勻高效的加熱，使其成為適于運輸、鋪設的黏稠液態。

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、過濾

瀝青材料在混合和加熱的過程中，可能會產生小顆粒的雜質。因此，必須通過過濾去除雜質。在這一流程中，常用多級過濾器，以準確濾出所需要的顆粒，而不會過濾掉瀝青中的有用成分。

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、儲存

經過加工后的瀝青需要進行儲存，儲存過程中需要保證瀝青的穩定性質量和純潔度。為了達到這個目的，通常采用封閉罐體進行儲存。

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.

以上就是公路瀝青生產工藝的流程，每個工序都需要注意質量和安全。

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