This depends on the type of paving job. Paving a driveway for a homeowner usually takes a half day to a full day, depending on the length, width and total area to be paved. A Commercial Parking Lot timeline varies, depending on the specifications and scope requirements for the job.
The short answer is YES! Asphalt is not unlike any other surface, it will deteriorate over time. As cracks form, water penetrates the surface, and freezing water expands causing larger cracks to form, or even causing potholes. Properly applying a sealcoat to your pavement will prevent water from penetrating small cracks, helping to extend the life of your pavement and your investment.
It is usually best to stay off a freshly paved surface for 3-4 days in warmer weather. Typically a warm spring and hot summers take longer for the soft asphalt to cool and harden. However, in cooler temps like in the fall, 1-2 days is usually sufficient.
