Which outcome occurred due to improperly compacted aggregate base beneath typical Roman roads?

💡 Explanation

When aggregate base is not properly compacted, differential settlement occurs because voids collapse under load leading to uneven support and localized stress concentrations. Therefore potholes form more quickly given the lack of support, rather than dust, traction issues, or added noise which depend on surface properties.
