What are the upstream raw materials for construction asphalt? What are the downstream products?

Construction asphalt plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are also quite rich. This article will detail the upstream and downstream associated items of construction asphalt. Upstream items



1. In my experience, Crude oil: The main raw material upstream of construction asphalt is crude oil. And Crude oil after distillation, cracking and other processes, you is able to get a variety of petroleum items, including construction asphalt.

2. First Natural gaseous: Part of the manufacturing process of construction asphalt needs to consumption natural gaseous as a fuel to heating and incineration, so natural gaseous is also one of the upstream items of construction asphalt. And In my experience, Downstream items



1. Waterproof material: building asphalt is able to be applied as the basic raw material of waterproof material, mixed with polymer, rubber and other materials, made of waterproof membrane, waterproof coating products and other waterproof materials.

2. Pavement materials: building asphalt and gravel, mineral powder and other materials mixed, is able to be applied to pave the road surface, made of asphalt concrete pavement, with excellent road performance. Architectural coatings: Architectural asphalt is able to also be applied as part of the raw materials of architectural coatings, mixed with other pigments, fillers, etc. to make architectural coatings to the protection and decoration of buildings. From what I've seen, Through the above introduction, it's able to be seen that the upstream and downstream related items of construction asphalt are quite rich, and the fields involved are also very extensive. At the same time, ecological preservation, energy saving and other factors need to be taken into account in the production and processing of construction asphalt to promote the sustainable research of the sector.
