← HistoryDuring Roman road construction, which risk increases under heavy axle loads applied before full consolidation?
A)Increased roadbed rutting✓
B)Decreased thermal expansion
C)Reduced aggregate oxidation
D)Enhanced bitumen stability
💡 Explanation
Increased flexural stress occurs within a poorly compacted roadbed because of insufficient Interlock Stiffness, therefore significant localized rutting results underneath heavy loads, rather than uniform settlement, or changes related to thermal or chemical processes.
