Which issue arises when inadequate drainage exists alongside a Roman road built on clay-rich soil?

💡 Explanation

When inadequate drainage exists, water saturates the clay soil, subsequently freezing and expanding; this ice formation leverages and displaces the road's paving stones and aggregate, increasing rutting. Therefore, rutting results from repeated freeze-thaw, rather than dust, compaction, or skidding which involves traffic or other conditions.
