A new asphalt driveway or parking lot, when properly installed and maintained, can last between 15 to 25 years. The lifespan is influenced by various factors including local climate conditions, the amount of traffic it receives, proper drainage, and regular maintenance practices such as sealcoating and addressing cracks promptly.

Newly laid asphalt can typically support light foot traffic within a few hours of installation. However, it's advisable to keep vehicles off the surface for at least 24 to 48 hours. During periods of hot weather, it may be beneficial to extend this waiting period to prevent potential tire marks or surface deformation.

Asphalt resurfacing involves applying a new layer of asphalt over the existing foundation, which is suitable when the underlying base is still in good condition. Full replacement, on the other hand, requires removing the old asphalt entirely and reconstructing the base. This method is recommended for surfaces with significant cracking, drainage problems, or structural issues.

Sealcoating is essential for asphalt as it provides protection against ultraviolet rays, water infiltration, oil spills, and oxidation. This protective measure extends the lifespan of the pavement and maintains its appearance. For optimal results, most asphalt surfaces benefit from sealcoating every two to three years.

The cost of asphalt paving varies significantly based on several factors, including the size of the project, asphalt thickness, necessary base preparation, and specific site conditions. Due to the wide range of variables for both residential driveways and commercial lots, paving companies typically offer complimentary on-site evaluations to provide accurate cost estimates.
