Which pavement type consists of porous surfaces that let water pass through to reduce runoff and flooding?

• A. Traveling salesman problem
• B. Permeable pavement
• C. Modular pavement
• D. Dead reckoning

Answer: (B)

Water management through pavement design uses porous surfaces to allow rainwater to pass through and infiltrate, reducing runoff and the risk of flooding. Permeable pavement is crafted with a porous surface and an underlying storage or filter layer so water can seep down rather than pool on top. This not only lowers surface runoff but also helps recharge groundwater and can improve urban drainage. You’ll see this approach in pervious concrete, porous asphalt, and interlocking paver systems with voids that let water move through. Other terms in the choices relate to topics outside pavement water management—one is about a mathematical optimization problem, another a navigation technique, and another a different pavement type that doesn’t emphasize permeability.
