Fortunately for homeowners, a crack that develops in an asphalt driveway is easily repaired. Crack repair products for asphalt driveways are available from any home supply store, farm supply store, or hardware store. Easy to use, these products can fill a crack as soon as it appears.
Repairing cracks as soon as they appear is important. Left open, a crack will retain water and allow it to infiltrate the sub-base. Over time, hydraulic pressure will enlarge the crack. The winter freeze/thaw cycle can worsen the problem, leading to the development of more cracks and even potholes. So, when a crack appears, don’t delay. Fill it with a high-quality blacktop driveway crack filler right away, and you’re back in business.
