What is an important factor to consider when grading a road?

Considering the moisture content of the soil is crucial when grading a road because it directly affects the soil's stability and compaction properties. If the soil is too wet, it can become muddy and lose its structural integrity, leading to difficulties in achieving a smooth and even grade. Overly dry soil, on the other hand, can result in dust and inadequate compaction, which may compromise the road's durability.

Monitoring moisture levels helps in determining the best time and approach for grading, ensuring that equipment can operate efficiently and that the finished road surface will be resilient to traffic and weather conditions. This attention to moisture ultimately supports the long-term performance of the roadway.

In contrast, factors such as the color of the gravel or the time of day do not play a significant role in the grading process, and while air temperature might have some minor impact on moisture evaporation, it doesn’t provide the direct insights required for effective grading decisions.
