← HistoryWhich risk develops on Roman roads experiencing continuous heavy wheeled vehicle traffic?
A)Longitudinal deformation (rutting)✓
B)Oxidative pavement disintegration
C)Hydrostatic subgrade compression
D)Transverse fracturing (buckling)
💡 Explanation
Longitudinal deformation (rutting) occurs from repeated stress exceeding yield strength of the road layers because plastic deformation accumulates in line with wheel paths, therefore rutting develops rather than widespread cracking due to stress concentration.
