What causes widespread exposure of pavement?

Widespread exposure of pavement can be caused by several factors, including weathering, erosion, and inadequate maintenance. Extreme weather conditions, such as heavy rainfall or freeze-thaw cycles, can lead to cracks and surface degradation. Additionally, heavy traffic loads and poor drainage can exacerbate wear and tear on pavement surfaces. Over time, these factors can contribute to the deterioration of pavement, leading to increased exposure and potential safety hazards.
