Which risk increased during Roman road construction if aggregates weren't compacted sufficiently within the statumen layer?

💡 Explanation

If aggregates weren't compacted sufficiently during statumen construction, soil consolidation occurs because increased void spaces decrease the load bearing capacity, leading to inconsistent settling across the road. Therefore road subsidence results, rather than rolling resistance, aqueduct issues, or vegetation, which require different weaknesses.

• Which environmental risk increased in Post-Classic Mesoamerica due to intensive chinampa cultivation within limited lake systems?
• Which risk increases when the hydraulic head exceeds design limits in a Roman aqueduct?
• Which outcome resulted when 16th century chinampa farmers near Tenochtitlan densely planted maize year-round without fallow periods?
• Which structural weakness significantly increased the risk of landslides along ancient Roman roads built on steeply sloped terrain?
• Which structural failure was most likely to occur if Roman concrete was cast without pozzolanic ash?
• Which effect arises when Roman roads experience differential seasonal ground heave?
