Which outcome occurred when ancient Roman roadbeds experienced increased groundwater saturation?

💡 Explanation

When roads absorbed ground water, bearing capacity declined because soil COMPACTION decreased. This increases the risk of differential Sinking/Settling, therefore the roads became uneven, requiring costly mitigation, rather than experiencing improved stabilization or decreased costs which depend upon solid foundations.
