Differences in How Blacktop and Asphalt are Made

When it comes to choosing a driveway material, blacktop and asphalt are two common options many homeowners consider. Despite the similarity in appearance, blacktop and asphalt differ significantly in their composition and application. In this article, we will explain the differences in how blacktop and asphalt are made.

Blacktop, also known as bituminous concrete, is a mixture of stone, sand, and liquid asphalt. The asphalt used in blacktop is a crude oil byproduct known as bitumen. The mixture is heated and poured onto a gravel or crushed stone base. The black color of blacktop comes from the addition of carbon black, a fine carbon powder that provides color and increases durability.

Asphalt, on the other hand, is produced by heating different grades of petroleum to a liquid state. Aggregate, which can include crushed stone, sand, and gravel, is then added to the liquid petroleum to create a strong, durable paving material. Hot mix asphalt, the most common type of asphalt, is produced at high temperatures, which makes it suitable for use on major roadways and airport runways.

While both materials require proper maintenance to last, blacktop is typically easier to repair. Blacktop surfaces are porous and can easily develop cracks and potholes, which can be fixed by filling them in with more blacktop mixture. Asphalt, however, is less porous and requires a layer of sealant to prevent water damage and cracking.

In summary, blacktop and asphalt are both durable materials used for paving surfaces, but their compositions and applications differ significantly. Blacktop, made from a mixture of stone, sand, and liquid asphalt, is usually used for residential driveways due to its low cost. Asphalt, produced by heating different grades of petroleum and adding aggregate, is used for major roadways and airport runways. Proper maintenance is crucial for both materials, but blacktop is typically easier to repair.
