Which property is the ability to withstand repeated loading without failure?

• A. Fatigue Resistance
• B. Durability
• C. Stability
• D. Workability

Answer: (A)

Repeated loading from traffic subjects pavement to cyclic stresses. The ability to withstand these cycles without developing cracks or failing is fatigue resistance. This property specifically captures how well the material resists crack initiation and propagation under many load cycles, which is how asphalt pavements typically fail under traffic. Durability is a broader idea about long-term environmental aging and wear; stability relates to performance under a primarily static load, and workability concerns how easy the mix is to place and compact. So fatigue resistance best describes the pavement’s performance under repeated loading.
