What is the expected lifespan of new asphalt pavement?

The expected lifespan of new asphalt pavement is typically 20 years or more. This figure can vary based on several factors, including the quality of the materials used, the construction techniques applied, maintenance practices, climate conditions, and the volume and weight of traffic that the pavement endures. Proper design, installation, and regular maintenance, such as seal coating and timely repairs, can significantly enhance the lifespan of asphalt. Therefore, it is widely recognized in civil engineering and public works management that well-constructed asphalt pavement can last two decades or longer under optimal conditions.
