It is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosive organic gelling material. At present, asphalt aging test equipment is mainly used to simulate the effects of various environmental factors (such as heat, oxygen, ultraviolet rays, etc.) on asphalt during long-term use to evaluate the performance changes of asphalt.
