You may have an asphalt or blacktop driveway as I do. Mine was installed 25 years ago and is in good condition. The mix ordered at the asphalt plant was key to its longevity. The stones in the mix are larger than normal.
Keep in mind that blacktop is much like concrete. It’s a blend of stones, sand, and liquid asphalt cement. The ingredients are tumbled in a large slanted drum, allowing the hot, sticky asphalt cement to thoroughly coat the stones and sand. Concrete uses Portland cement and water to interlock the stones with the sand.
