Although asphalt driveways are amazingly durable, the surface can become pitted and cracks can appear. Fortunately, you'll find your local home center, building supplies dealer or hardware store stocked with many products to stem the tide. Slightly larger holes are filled with asphalt patch mix. Serious potholes are best handled with a coarse aggregate filler commonly called cold patch. After the cracks and holes are filled and leveled, the driveway is coated with driveway sealer.
Typical sealers are coal-tar based.
This product is also available as a combination sealer and filler with a fine aggregate added to help smooth rough and pitted pavement. Acrylic-based sealers are also available. In addition to the sealer, you'll need to buy applicators with a brush on one side of the head and a squeegee on the other. Preparation Driveway maintenance products need to be applied on relatively warm, dry days when you don't foresee rain for the next few days. Also, be prepared to keep your driveway out of service for the following day or so to allow the sealer time to dry.
