What impact does improper grading technique generally have?

• A. Enhances road durability
• B. Leads to increased maintenance costs
• C. Improves visibility on construction sites
• D. Reduces the need for slope indicators

Answer: (B)

Improper grading technique typically leads to increased maintenance costs. When roads are not graded correctly, issues such as uneven surfaces, poor drainage, and insufficient compaction can arise. These problems often necessitate more frequent repairs and maintenance work, which can significantly elevate operational costs over time. For instance, if water is allowed to pool on an improperly graded surface, it can cause erosion and damage the road foundation, requiring costly fixes. The other choices do not accurately reflect the consequences of improper grading. Enhancing road durability or improving visibility does not occur with poor grading; instead, the structural integrity of the road is compromised. Similarly, reduced need for slope indicators is irrelevant, as improper grading may actually increase the need for more precise control of slopes to mitigate risks associated with instability.
