During Roman road construction, which outcome was directly mitigated by the use of a 'statumen' layer beneath the 'rudus'?

💡 Explanation

Differential settlement was mitigated. The 'statumen' (large stones) distributed loads, using the principle of load distribution, thereby minimizing uneven compression of the subgrade because the load is spread, therefore reducing sinking in some areas, rather than uniform soil compaction.
