Which consequence frequently resulted when Roman military roads lacked sufficient drainage channels during the Republic?

💡 Explanation

Insufficient drainage promoted water accumulation within the roadbed, accelerating differential expansion. This freeze-thaw cycle caused accelerated material disintegration, a form of frost heave, because water expands when freezing; therefore roadbeds weakened rather than enabling better maneuverability under stress.
