According to previous studies and field investigations, asphalt pavement is affected by volatilization, absorption, oxidation, and photochemical reactions of the pavement, and the asphalt ratio drops sharply under initial aging conditions, resulting in a brittle and fragile pavement. With further erosion of the asphalt, the moderately aged pavement exposes its content. Asphalt pavement enters the aging stage due to continuous tearing and weathering, in which the stones are exposed to smaller particles on the pavement.

During the aging process, the deformability and structural strength of the pavement decrease.  Eventually, extensive road pavement distress occurs in the form of linear cracks, alligator cracks, potholes and rutting. This process greatly reduces viscosity and brittleness, increases ductility and flexibility, and makes asphalt less prone to cracking and deterioration.
Unlike old-fashioned seal coatings, a single application of asphalt regeneration test section penetrates the pavement to restore and replace the tar and asphalt lost due to oxidation surface far less than the protected asphalt. It also seals and protects the pavement from water, sunlight and chemical pollutants, greatly improving durability, life and reducing the attractiveness of asphalt. Asphalt mixing manufacturers remind you that proper maintenance is the key to protecting asphalt from external factors that wear and tear.
