Which constraint most increased the Roman roads' lifespan?

💡 Explanation

The Roman roads endured because drainage reduced hydrostatic pore pressure, mitigating frost heave and erosion; therefore, the structural integrity was maintained, rather than succumbing to gradual disintegration from internal pressures.
