What factor does NOT contribute to the condition evaluation of pavements for rehabilitation?

• A. Pavement age
• B. Type of traffic
• C. Surface texture
• D. Temperature variations

Answer: (D)

The evaluation of pavement condition for rehabilitation typically considers various factors that directly impact the pavement's performance and longevity. While pavement age, type of traffic, and surface texture are all critical elements influencing the wear and tear of road surfaces, temperature variations do not directly contribute to the evaluation of pavement condition in the same manner. Pavement age factors into the evaluation since older pavements are generally more prone to deterioration due to extended exposure to traffic loads and environmental conditions. The type of traffic, including vehicle loads and volume, can significantly affect the stresses imposed on the pavement, which is vital for assessing its condition. Surface texture is another crucial component because it influences skid resistance and overall safety, indicating the need for potential rehabilitation. In contrast, temperature variations can impact pavements over time but are not a direct measure of their current condition. Temperature fluctuations may lead to thermal cracking or other distresses over time, yet they do not provide an immediate assessment of the existing pavement state. Therefore, while temperature changes play a role in pavement performance, they are not central to the condition evaluation process for rehabilitation decisions.
