Which problem increased on Roman roads during the empire's expansion impacting transport efficiency?

💡 Explanation

As the Roman empire expanded, the volume of traffic on roads increased, and the increased axle loads caused cumulative surface deformation and rutting because of material yield under repeated stress. Therefore rutting increased, rather than salting, lower tolls, or labor shortages, which concern other issues.
