Potholes usually begin with small cracks in asphalt that are not repaired promptly with crack-fill. When gaps are left unrepaired, water quickly erodes the asphalt sub-base, creating voids that eventually turn into potholes. Untreated cracks will continue to expand, making it critical to fix cracks as they appear to prevent more potholes from forming.
How do we fix potholes?
It’s vital to stay proactive with your asphalt pavement maintenance, including annual crack filling and infrared patching of potholes. Crack-filling is a proven maintenance technique to help keep water from entering cracks and deteriorating the asphalt sub-base and can prevent new potholes from forming.
