Pot Holes

英语百科

Pothole

Factors leading to pothole failure by fatigue in areas subject to freezing and thawing are: 1. Precipitation adds moisture to supporting soil structure. 2. Frost heaving can damage pavement. 3. Thawing can weaken soil structure. 4. Traffic can break the pavement.
A deep pothole with a nearby patched area on New York City's Second Avenue.

A pothole is a type of failure in an asphalt pavement, caused by the presence of water in the underlying soil structure and the presence of traffic passing over the affected area. Introduction of water to the underlying soil structure first weakens the supporting soil. Traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement.
