A chip ‘n’ seal driveway isn’t for everyone, but it can come in useful in certain circumstances including on roads and driveways that don’t see as much as traffic. The key is understanding when chip seals are the best option above concrete or regular asphalt.
The basic idea behind chip sealing is to create alternating layers of asphalt and aggregate. The reason why it’s a popular choice is that it’s usually cheaper than using regular asphalt or concrete, and while it might not be as durable as the other options, it’s better than leaving paths completely untreated.
One of the advantages to using chip seals is that they can stop water from getting into pavements and repair existing roads that would otherwise have needed completely resurfacing. It offers good skid resistance for passing vehicles while simultaneously protecting the road surface from aging and exposure to the elements.
