The manifestation and harm of asphalt pavement aging

According to previous research and on-site investigation, the asphalt pavement is affected by the volatilization, absorption, oxidation and photochemical reaction of the pavement. Under the initial aging conditions, the proportion of asphalt drops sharply, resulting in fragile and fragile road surface.

As the asphalt is further eroded, the moderately aged pavement exposes its content.

Asphalt pavement enters the aging stage due to continuous tearing and weathering, and the particles exposed to the pavement are smaller.

During the aging process, the deformation and structural strength of the road surface are reduced.

In the end, extensive road pavement distress occurs in the form of linear cracks, crocodile cracks, potholes and ruts.

This process greatly reduces viscosity and brittleness, increases ductility and flexibility, and makes asphalt less prone to cracking and deterioration.

Unlike the old-fashioned sealant coating, the single application of the leaching regenerative test section penetrates the pavement recovery and replaces the loss of tar and bitumen because the oxidation surface is much lower than the protective asphalt.

It also seals and prevents water from the pavement, sunlight and chemical contaminants, greatly improving durability, life and reducing the attractiveness of asphalt.

Asphalt mixing plants remind you that proper maintenance is the key to protecting asphalt from external factors.
