Questions & Step-by-Step Solutions

What is the primary benefit of using flexible pavement over rigid pavement?
  • Step 1: Understand what flexible pavement is. It is made of layers of materials that can bend and flex under pressure.
  • Step 2: Understand what rigid pavement is. It is made of concrete slabs that are strong but do not bend.
  • Step 3: Compare the costs of both types of pavement. Flexible pavement usually costs less to install than rigid pavement.
  • Step 4: Recognize that lower initial costs mean that flexible pavement can save money for projects.
  • Step 5: Conclude that the primary benefit of using flexible pavement is its lower initial cost, making it a more economical choice.
