Asphalt is one of the most commonly used materials in the construction of roads, parking lots, and driveways. But how does this versatile material stand the test of time and perform under the weight of constant traffic and varying weather conditions? Let's explore the science behind asphalt and why it’s the preferred choice for paving. At its core, asphalt is made up of two key components: aggregates (such as sand, gravel, or crushed stone) and bitumen, a sticky, black substance derived from petroleum. This mixture forms a durable, flexible surface capable of withstanding heavy loads and temperature fluctuations.
