What is one of the types of concrete disintegration defect in pavement?

Scaling is a specific type of concrete disintegration defect commonly observed in pavement. It refers to the flaking or peeling away of the surface layer of the concrete. This defect typically occurs due to the impact of environmental factors, such as freeze-thaw cycles, where moisture penetrates the surface and subsequently freezes. When the water freezes, it expands, which can cause the surface to crack and eventually lead to the loss of pieces of concrete, creating a rough texture.

Scaling can be problematic as it compromises the structural integrity of the pavement and can lead to further deterioration if not addressed promptly. Understanding scaling as a defect helps in identifying issues in pavement maintenance and implementing appropriate repair techniques to ensure the longevity and safety of the pavement. Other types of defects, while significant in their own right, do not fall under the specific category of concrete disintegration in the same way scaling does.
