Paving asphalt is a mixture of petroleum byproducts, fillers, binders, and aggregates like sand and stones. Asphalt is one of the most popular paving materials in the world due to its affordability and versatility.
If you’ve driven down a back-country road, a fancy driveway, or used passage roads along farmland, you’ve likely driven on top of chip seal, the ‘original’ paving style. In a chip seal road, a thin layer of asphalt is laid down before layers of crushed stone and aggregate are compacted on top of the asphalt.
Chip seal is also known as macadam, named for a Scottish pioneer for paved roads. The engineer John McAdam invented the revolutionary crushed stone layer roads with binders in the early 1800s. Though modern chip seal takes advantage of better binders, they still resemble McAdam’s macadam style roads.
Both asphalt and chip seal have their unique advantages and disadvantages. If you need a low-traffic passage for your backcountry property, chip seal can likely do the job but if you need a long-lasting driveway for your suburban home, you’ll need the durability of asphalt.
