Temperature makes a difference when it comes to paving or repaving your driveway. A professional contractor will be laying the asphalt hot, and they’ll have to maintain that temperature for a steady and even pour. The outside temperature will affect the temperature of the asphalt as it cools and cures. For this reason, you don’t want the weather to be too cold or too hot. A drastic swing in either direction could result in an unsuccessful, uneven pour.
