Which outcome manifested when sections of the Roman Appian Way experienced differential settling on heterogeneous ground?

💡 Explanation

When Roman roads experienced differential settling, stress concentration occurs because varying soil compositions caused uneven compaction, leading to cracking and void formation. Therefore, potholes and accelerated degradation result, rather than improved drainage, stability, or aesthetics, which require uniform support and construction.

• Which consequence results when rainfall exceeds drainage capacity on steeply terraced Andean farmland?
• Which outcome increases when seasoning timber too rapidly during wooden ship construction?
• Which structural adaptation allowed Hagia Sophia's dome to surpass earlier Roman domes in diameter?
• Which outcome resulted during Roman siege warfare when defending city walls lacked counterweight trebuchets?
• Which mechanical consequence arises when silt accumulation reduces Mesopotamian canal slope?
• Which structural consequence appears from geometrically similar arches not scaled proportionally with varying span?
