Which advantage did properly cambered Roman roads provide during periods of heavy rainfall?

💡 Explanation

When it rained, cambered roads facilitated efficient drainage because gravity-driven flow directed water to the sides, minimizing pooling and hydroplaning risk. Therefore reduced standing water is achieved, rather than infiltration, expansion mitigation or camouflage which serve completely unrelated purposes or rely on alternative geometries.
