How do Potholes Form?
Potholes begin with cracks in asphalt that are not repaired promptly. When cracks are left unrepaired, water infiltrates and erodes the asphalt sub base, creating voids which turn into potholes. Untreated cracks will continue to grow downward into asphalt and outwards on top of pavement, making it essential to fix cracks as they appear if you want to prevent more potholes from forming.
New Jersey has severe freeze/thaw cycles during winter that accelerate the process of crack and pothole formation. This is why new potholes can pop up seemingly overnight coming out of winter as the weather improves and the ground thaws out.
How are Potholes Repaired?
Infrared patching is a permanent repair solution that can last for years. It’s also the quickest, most cost-effective and most environmentally friendly way to repair most potholes. The conventional repair method involves full depth reconstruction where an area of pavement is cut out completely and rebuilt through milling and repaving, which is costly, and requires much more material and labor. With infrared patching technology, you get a lasting repair, even during extreme cold weather, so it doesn’t evolve into a larger problem.
It’s important to stay proactive with pavement maintenance, which includes annual crack filling and infrared patching of potholes. Crack-filling is a proven maintenance procedure to help keep water from entering cracks and deteriorating asphalt sub base, and can prevent new potholes from forming.
