Asphalt is a black, sticky substance made from a mixture of sand, gravel, and bitumen, which is a thick, tar-like material. It is commonly used for paving roads, parking lots, and driveways because it creates a smooth and durable surface. When heated, asphalt becomes pliable, allowing it to be easily spread and shaped before it cools and hardens. In addition to roads, asphalt is also used in roofing materials and waterproofing products. Its ability to resist water makes it ideal for protecting buildings and structures. Many cities rely on asphalt for their infrastructure, making it an essential part of modern urban life, alongside concrete and pavement.
