A comprehensive comparison of two popular paving materials to help you choose the right option for your project
While often used interchangeably, there are key differences between asphalt and blacktop:
Asphalt is a mixture of aggregates (crushed stone, sand, and gravel), binder (bitumen), and filler materials. The standard asphalt used for roads and highways typically contains about 5% bitumen and 95% aggregates. It's manufactured at temperatures between 200-250°F and is known for its durability and versatility.
Blacktop is a specific type of asphalt mixture that contains a higher percentage of stone materials and is manufactured at higher temperatures (around 300°F). The additional stone gives blacktop its characteristic appearance and slightly different performance properties. Blacktop is often used for residential driveways and smaller projects.
| Feature | Asphalt | Blacktop |
|---|---|---|
| Composition | 5% bitumen, 95% aggregates | Higher stone content, slightly less bitumen |
| Manufacturing Temperature | 200-250°F | Around 300°F |
| Appearance | Dark gray to black | Deeper black, more polished finish |
| Durability | Highly durable, 15-20 years with proper maintenance | Slightly more brittle, 12-15 years typical lifespan |
| Cost | $2-$5 per square foot | $3-$7 per square foot |
| Best Applications | Highways, roads, commercial parking lots | Residential driveways, basketball courts, playgrounds |
| Maintenance | Sealcoating every 3-5 years | Sealcoating every 2-3 years |
Many people use the terms "asphalt" and "blacktop" interchangeably, but as we've seen, there are technical differences between them. In everyday conversation, both terms often refer to the same black paving material used for roads and driveways.
