Which method is commonly used for assessing the effectiveness of roadway grading?

The method commonly used for assessing the effectiveness of roadway grading is visual inspection. This approach allows engineers and inspectors to evaluate the surface of the roadway for uniformity, smoothness, and adherence to design specifications. Visual inspection can quickly identify issues such as ruts, dips, and drainage problems that may affect the overall performance of the roadway. Observations made during visual inspections can guide maintenance and improvement actions before any more technical assessments or tests are required.

While other methods like compaction testing, load-bearing tests, and surveying may provide quantitative data on pavement strength and geometric measurements, they are not primarily focused on evaluating the surface conditions of the grading itself. Instead, these methods serve specific purposes such as ensuring proper material compaction or determining load capacity, rather than assessing overall grading effectiveness as directly as visual inspection does.
