Which limitation arose for Roman roads nearing collapse from heavy use?

💡 Explanation

Road collapse occurs because of repeated stress exceeding the yield strength, inducing plastic deformation. This compromised load-bearing ability causes subsidence and cracking; therefore, they require constant maintenance and redesign, rather than preventing sediment transport or expanding drainage systems.
