While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.

Yes, using recycled asphalt millings is an eco-friendly alternative compared to concrete. Millings are reclaimed pieces of gravel that are recycled into aggregate that can be used on driveways, patios, walkways, basketball courts, tennis courts, and more.

If you notice minor cosmetic problems with your driveway, you should seal it. Look out for cracks and holes on the surface, faded asphalt or concrete, and stains from oil and other chemicals. Replacing your driveway may be necessary if you’re dealing with significant problems—¼-inch cracks, large potholes, and puddles from drainage issues. The cost to install an asphalt driveway typically ranges between $4,200 and $9,000, significantly more than resealing. Consider talking to a professional to discuss whether resurfacing your driveway—a midway project between resealing and replacing—is a better option for you.

The layer of polymeric sand under the pavers plus the polymeric sand that gets swept into the joints between your pavers holds them in place in a few ways. For one, the gritty texture of the sand helps lock the pavers together. Polymeric sand also contains bonding agents that get activated by water. Polymeric sand will take between 24 and 48 hours to fully cure, so do not walk on your paver walkway before this time.
