Which outcome results when Roman road construction encounters unstable soil conditions?

💡 Explanation

When Roman road construction encounters unstable soil, differential settlement occurs because varying soil compaction leads to unequal load distribution, causing the road surface to crack. Therefore increased road surface cracking results, rather than blockage, collapse, or tilting which require different geological and structural conditions.
