What is the main advantage of using concrete over asphalt for pavement?
Step 1: Understand what concrete and asphalt are. Concrete is a mixture of cement, water, and aggregates, while asphalt is made from bitumen and aggregates.
Step 2: Learn about the lifespan of both materials. Concrete pavements can last 30-40 years, while asphalt typically lasts 15-20 years.
Step 3: Recognize that a longer lifespan means less frequent repairs and replacements for concrete.
Step 4: Consider the cost over time. Even though concrete may be more expensive initially, its longer lifespan can save money in the long run.
Step 5: Conclude that the main advantage of concrete over asphalt is its longer lifespan, which makes it beneficial for certain projects.
