What is the expected lifespan of typical asphalt pavement?

• A. 10 to 15 years
• B. 15 to 25 years
• C. 25 to 35 years
• D. 30 to 40 years

Answer: (B)

The expected lifespan of typical asphalt pavement is generally considered to be between 15 to 25 years. This range is based on various factors including usage, climate, maintenance practices, and the quality of the materials used during construction. Asphalt pavement is designed to withstand a certain amount of traffic load, environmental conditions, and wear over time. Regular maintenance such as seal coating, crack filling, and timely repairs can help extend its lifespan, often pushing it closer to the higher end of the range. In contrast, options that suggest a lifespan shorter than 15 years would not account for the durability that asphalt can provide when properly maintained, while options suggesting a lifespan longer than 25 years may overlook the inevitable degradation due to factors like weathering and traffic stress. Thus, the range of 15 to 25 years is a practical and widely accepted estimate for asphalt pavement.
