Properly maintaining your asphalt driveway or parking lot can save you a significant amount of money over time. Asphalt is a strong and reliable material, but it requires regular care to maintain its durability. Cracks in your asphalt surface allow water to seep in, reaching the soil beneath. This leads to destabilization and, in colder conditions, water can freeze, expanding and worsening the cracks. To prevent this damage, timely crack repairs along with regular sealcoating are essential. Below is a guide on how to repair cracks in asphalt effectively.
1. Check the Weather and Prepare the Driveway
Before beginning any asphalt repair, always check the weather forecast. It's crucial that there is no rain expected during the repair process, as moisture can interfere with the bonding of repair materials. Additionally, the temperature should be between 50 and 90 degrees Fahrenheit for optimal conditions.
Next, prepare the surface. Clear the area of all debris using a leaf blower or broom, making sure to clean out the larger cracks. If you're also planning to sealcoat, trim back any grass or vegetation along the edges of the driveway. Avoid using water unless you're certain there is enough time for the surface to dry completely.
2. Prepare the Cracks
Larger cracks are straightforward to repair, but smaller cracks may require some additional preparation. Use a diamond pad on a grinder to widen smaller cracks, making them easier to fill. Inspect all cracks to ensure they are free of dirt and debris. Proper cleaning is crucial, as any debris trapped inside the crack can prevent the repair material from adhering properly, resulting in a less durable fix.
3. Fill the Cracks
Repairing cracks in asphalt is easier than many expect. For cracks that are 1/2” wide or smaller, use a bottle crack filler, which has self-leveling properties. Simply apply the filler along the crack using the bottle’s nozzle, much like dispensing glue. Be careful not to overfill, as a small amount of filler is usually sufficient.
For larger cracks and holes, you will need a cold patch. Fill the crack with the cold patch material and use a trowel or tamper to level it off. Avoid sealing the patched area for four to six weeks to allow the repair to fully settle and cure.
