You can pour concrete over asphalt if it’s in good condition, thick, stable, and well-compacted. Concrete is more durable than asphalt and can extend the lifetime of your driveway without having to pay frequent asphalt driveway repair costs or replace it completely. 

But this is best reserved as a temporary solution based on budget restraints, as asphalt requires more frequent repairs and assessments than concrete. Once that concrete top is poured, it’ll be harder to accurately understand what’s happening beneath that layer, which could lead to more issues.

Depending on project size, typically 1 to 3 days, including preparation and installation.

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.

Yes, hardscaping is generally a great investment that can increase your home's value. Hardscape features improve your yard's functionality, safety, and aesthetics, which boosts curb appeal and overall property value. According to a survey by the National Association of Realtors and the National Association of Landscape Professionals, hardscape upgrades are one of the top four outdoor projects that add value to a property for resale, along with landscape upgrades, landscape management, and lawn care services. While most buyers see value in these features, some may be concerned about potential increases in property taxes or the cost to alter them later. However, the return on investment is typically excellent. For best results, hardscaping should be combined with professional landscaping, and it's wise to hire a reliable contractor for installation.
