Which outcome results when Roman road construction exceeds maximum grade limits?

💡 Explanation

Exceeding maximum grade limits leads to increased erosion. The mechanism is increased runoff velocity because steeper slopes enhance the gravitational force accelerating the water. Therefore, roads wash away faster with increased surface and structural damage, rather than improved drainage effects.
