The production principle and biggest features of rubber asphalt
There are many types of asphalt on the market, so how much do we know about the production principle of rubber asphalt? Let's take a look together.
Rubber asphalt is a modified asphalt binder material formed by first processing the original waste tire into rubber powder, then combining it according to a certain coarse and fine grading ratio, adding a variety of high polymer modifiers, and fully melting and swelling with the matrix asphalt under high temperature conditions (above 180°C) with full mixing. It is generally understood as asphalt with rubber added. Rubber asphalt has high temperature stability, low temperature flexibility, anti-aging, anti-fatigue, and water damage resistance. It is an ideal environmentally friendly pavement material and is mainly used in the stress absorption layer and surface layer of road structures.
