Types of cracks in asphalt

- Alligator cracks: A series of interconnected cracks that form a pattern resembling alligator skin, indicating severe damage.
Choosing the right crack filler
When selecting a crack filler, consider the crack type, expected temperature fluctuations, and whether there's any movement in the pavement. Here’s a breakdown of common crack fillers:
