What is the method for taking roadway samples?

The method for taking roadway samples typically involves collecting a minimum of three combined increments. This approach ensures that the sampling reflects a more accurate representation of the roadway conditions across the specified area. By taking multiple increments, any variability in the material or conditions can be accounted for, leading to more reliable data regarding the quality and characteristics of the roadway.

Combining increments allows for a comprehensive overview rather than relying on a single measurement, which could be an anomaly or not represent the general condition adequately. This method is often used in engineering and construction practices to maintain consistency and reliability in results, making it essential for proper analysis and decision-making in earthwork projects.
