What problem can improper leveling and adjustment lead to during pavement construction?

• A. High or low spots and increased movement risk.
• B. Faster installation.
• C. Improved drainage.
• D. No impact.

Answer: (A)

Uneven surface elevations undermine a stable, uniform base. When leveling and adjustment aren’t done properly, the finished pavement ends up with high spots and low spots, so loads aren’t supported evenly. This causes differential settlement and localized stresses that can lead to movement under traffic, cracking, and misalignment at joints. In short, improper leveling creates high or low spots and increases the risk of movement, which is the primary problem. Faster installation isn’t a benefit of poor leveling, and drainage isn’t improved by uneven surfaces—low spots can trap water and worsen damage rather than help drainage. Saying there’s no impact ignores the clear ways uneven support translates into performance issues.
