How long does Asphalt typically last?

• A. 10 to 15 years
• B. 30 to 40 years
• C. 15 to 20 years
• D. 40 to 60 years

Answer: (C)

The length of time asphalt lasts depends on traffic loads, climate, and how well the surface is maintained. Asphalt is subject to wear from vehicle or aircraft movement, cracking from temperature changes, and moisture effects, so its life is tied to how well these factors are managed. In typical airport or roadway practice, with proper design and regular upkeep such as crack sealing, seal coats, and timely resurfacing, the expected service life is around 15 to 20 years. This range represents a balance where the pavement remains functional and safe before major rehabilitation is needed. If maintenance is delayed or loads are unusually heavy, the pavement can deteriorate sooner. Conversely, with excellent materials, good drainage, and timely rehab, some pavements can approach the upper end of that range. The other options—shorter than 15 years or extending to 30–60 years—don’t align with common asphalt performance patterns, since longer lifespans are more typical for well-maintained concrete pavements or require significantly different design and maintenance strategies.
