The hidden engineering of why roads inevitably crumble
In short: Potholes are rarely random accidents. This video explores the slow, systematic degradation of pavement, revealing how tiny cracks and environmental forces work together to destroy road foundations from the inside out.
The video examines the lifecycle of a pothole, moving from the visible asphalt surface to the hidden engineering layers beneath. It explains how a minor crack serves as a gateway for water—one of pavement's primary enemies—to infiltrate the road structure.
Key factors contributing to this decay include the weight of vehicles, fluctuating temperatures, and the destructive cycle of freezing and thawing. By understanding these mechanics, the video explains why simple repairs often fail to prevent potholes from recurring.
