34. Which property of aggregate is crucial for determining the resistance of asphalt mixes to rutting?
- Aggregate hardness
- Aggregate shape
- Aggregate size
- Aggregate gradation
Answer
The correct answer is: B) Aggregate shape
Explanation
Aggregate shape plays a significant role in resisting rutting in asphalt mixes. Angular and rough-textured aggregates provide interlocking characteristics, reducing rut formation under traffic loads.
