The most obvious disadvantage of permeable paving is that the cost is typically higher compared to non-permeable concrete, pavers, or asphalt methods. Also, the porous material can get clogged with dirt and debris, requiring cleaning and power washing more frequently than standard paving materials and methods. Although permeable paving is not ideal for highways, airports, and other surfaces supporting heavy traffic and machinery, it is suitable for regular residential driveways.

Asphalt dries and cures best between 50 and 85 degrees Fahrenheit. This range allows moisture to evaporate quickly without causing the asphalt to cool too fast, which can negatively affect the drying process. However, keep in mind that other weather conditions can also affect curing and drying times, such as precipitation and humidity.

It takes recycled asphalt 48 hours to initially harden and up to 3 months to fully cure. It’s best to stay off of recycled asphalt for at least 48 hours, then you can walk or drive standard vehicles on it. Hold off on driving heavy trucks or equipment on it for at least 7 days. Allowing the surface to melt together and harden ensures that the surface stays durable and long-lasting. 

Paving is a part of hardscaping, so all paving is hardscaping, but not all hardscaping is paving. Paving involves laying down concrete or asphalt, while hardscaping can also include the use of paving stones, bricks, gravel, wood, and more. Hardscape features that involve paving are considered permanent and will increase your property taxes, while some other hardscaping features—like those involving bricks, gravel, and paving stones—will not affect property taxes. Paving also typically requires a permit, while hardscaping features considered temporary will not.
