Which outcome occurs when the subgrade of a Roman road saturates?

💡 Explanation

Saturation of subgrade soils reduces their bearing capacity, causing pavement pumping due to repeated loading. Increased pore pressure weakens the aggregate support because water expels fine particles; therefore the pavement fails prematurely rather than maintaining its integrity under constant usage.
