Which consequence results when excessive groundwater permeates a Roman road?

💡 Explanation

Increased roadbed heaving occurs because water expands upon freezing via ice lens formation, leading to frost heave damage. Ice lenses concentrate near the surface; therefore, the surface heaves outward, rather than forming deeper structural changes.
