For a single sack stockpile aggregate sample, where are samples taken from?

When collecting a single sack stockpile aggregate sample, it is essential to ensure that the sample accurately represents the material contained in the entire stockpile. Sampling from the top, middle, and bottom of the pile allows for a comprehensive distribution of the sample, capturing potential variations in material throughout the different layers. This method is effective in achieving a representative sample by minimizing the risk of bias that might occur if the sample were taken from only one location within the pile.

By taking samples from multiple elevations (top, middle, and bottom), the inspector reduces the likelihood of overlooking variations in aggregate properties, such as gradation or moisture content. This method is in line with industry best practices, which emphasize the importance of representative sampling to ensure quality control in aggregate materials.
