Why do pavements crack?
Following initial construction, pavement begins the process of oxidation. Over time, it becomes dry, brittle, more rigid, and less flexible. The aggregate starts wearing away, causing cracks. Some small cracks can start to show in the first year of new pavement. The City of Oak Forest provides a quality maintenance program to extend the life cycle of asphalt up to 30 years, saving taxpayers money while providing safe and efficient roadways.
