During pavement evaluation, what does skid resistance indicate?

• A. Surface quality
• B. Load-bearing capacity
• C. Durability against weathering
• D. Temperature sensitivity

Answer: (A)

Skid resistance is a critical parameter in pavement evaluation, primarily indicating the surface quality of the pavement. This measurement assesses how well a vehicle tire can grip the pavement surface under various conditions, especially during wet weather when the risk of skidding or slipping is heightened. High skid resistance is essential for ensuring vehicle safety, as it minimizes the likelihood of accidents caused by loss of traction. The other factors listed—load-bearing capacity, durability against weathering, and temperature sensitivity—focus on different aspects of pavement performance. Load-bearing capacity pertains to how much weight a pavement can support without failing, durability against weathering relates to the pavement's ability to withstand environmental elements over time, and temperature sensitivity addresses how pavement materials react to temperature fluctuations. While these factors are crucial to pavement longevity and performance, they do not directly reflect its skid resistance, which is solely about maintaining adequate friction between tires and the road surface.
