There are several factors that will determine when is the best time of year for paving your asphalt driveway. Consider the following variables when you plan this project.
Best Weather Conditions
Asphalt paving is a very hot liquid, but that doesn't mean it can be used at any time. While you may have seen crews on the highway laying asphalt in various types of weather, it is not necessarily versatile. Asphalt has a cooling off time or workable time. If it cools too quickly, it will develop clumps and bumps that can't be fixed without tearing up the whole driveway and starting over again.
In general, the best times to pave an asphalt driveway are during periods of warm weather, like summer, early fall and late spring.
Another factor that affects asphalt paving is depth. The thicker the driveway will be, the longer you will have to lay and smooth the asphalt. A 4 inch thick driveway will have about 50 percent more hot or curing time to smooth it than a driveway half that thick.
Professional pavers are use to working with asphalt so they may be able to extend the times because of their proficiency. This is a job best done by professionals.
