The bigger issue for residential asphalt driveways is cracks. Cracks that allow water to penetrate into the gravel base are a far greater threat to the long-term health care of your driveway. Water that enters the gravel base can then soften the soil under an asphalt drive. If this happens, the weight of the cars going over this soft area can cause the paved surface to crack in even more places. Remember, asphalt paving is actually a flexible pavement. The strength of asphalt surfaces comes from strong soils and a strong base material under the finished surface.

Keep in mind that asphalt sealers are simply coatings that penetrate slightly into the asphalt surface. For the most part, they lay on top of the pavement. If you seal too often, you simply are adding layers of asphalt that can peel off. Asphalt drives should be sealed when you can clearly see the color of the stones that are used to make the asphalt paving.

When you purchase asphalt crack and driveway sealers, use pricing as a barometer. Usually higher priced products contain higher quality materials. Pay attention to any temperature limitations on the product labels. Be sure the products can cure properly.
