Heavy asphalt plays an important role in the field of raw materials for chemical production, and its upstream and downstream related products are quite abundant. The following are some major upstream and downstream related products:

Upstream products:

1. Crude oil: The main raw material of heavy asphalt is crude oil. By refining the residual oil component in crude oil, the raw material for the production of heavy asphalt can be obtained.
2. Residue: Residue is a by-product of the crude oil refining process and is a key raw material for the production of heavy asphalt.

downstream products:

1. modified asphalt: on the basis of heavy asphalt, by adding modifiers, you can produce more excellent performance of modified asphalt, used in high-grade highways, bridges and other construction.
2. emulsified asphalt: the heavy asphalt and emulsifier, water and other mixing, can produce emulsified asphalt, used for pavement maintenance, waterproof and other projects.
3. Asphalt mixture: The asphalt mixture can be produced by mixing heavy asphalt with mineral aggregate, which can be used for pavement construction and other engineering construction.

In addition, the upstream and downstream related products of heavy cross asphalt also include some auxiliary materials and additives, such as anti-stripping agents, anti-rutting agents, etc. These products can improve the performance and quality of heavy cross asphalt.

In summary, the upstream and downstream related products of heavy asphalt are quite rich, and their application fields are also very wide, and they have an important position in the field of raw materials for chemical production.
