Which consequence arose from improper placement of Roman road drainage culverts?

💡 Explanation

Increased frost heave cracking occurred because of water accumulation triggering freeze-thaw cycles which expanded the road materials via ice lens formation; therefore, road surfaces decayed faster because of lack of proper drainage, rather than only aggregate failure or load failure.
