What characteristic do strong pavements exhibit compared to weak pavements under testing?

• A. Stronger pavements deflect more
• B. Weaker pavements deflect less
• C. Strong pavements tend to deflect less
• D. Weak pavements are more durable

Answer: (C)

Strong pavements are characterized by their ability to resist deformation under load, which is why they tend to deflect less compared to weaker pavements during testing. This lower deflection indicates a higher structural integrity and better load-bearing capacity. Strong pavements utilize materials and design techniques that enhance their durability, enabling them to maintain their shape and functionality under traffic loads. In contrast, weaker pavements demonstrate greater deflection when subjected to similar loads, which can lead to structural failures over time. If pavements deflect excessively, they can develop issues such as cracking, rutting, and other distress that compromise road safety and longevity. Thus, the relationship between pavement strength and deflection is crucial in evaluating pavement performance and ensuring maintenance strategies are appropriate for extending the lifecycle of the pavement.
