What causes Asphalt damage ?

Cracks in asphalt occur when the earth underneath the pavement shifts for some reason. This could be due to seasonal changes in weather and humidity. Asphalt is designed to resist this moisture penetration, since it has glue keeping the aggregate material together. Even still, asphalt is not impermeable to water damage, especially in a driveway.When cold water sinks into or below the asphalt, it will freeze when temperatures drop. Freezing water expands, interfering with the stickiness of the glue. At some point, the water defrosts and shrinks, putting structural strain on the pavement. Pavement may buckle and make small fissures or larger cracks.
