From which locations of a stockpile should material be loaded out?

Loading material from various locations within a stockpile, specifically the front, center, and back, ensures a more uniform and consistent composition of the material that is being extracted. By sampling from different areas, the mixture can better reflect the overall quality and characteristics of the stockpile. This approach reduces the risk of variability that might occur if material is only taken from a single location, such as just the front or the center.

Additionally, extracting from multiple locations minimizes the potential for segregation, where different sizes or types of aggregates might separate within the stockpile, leading to uneven material properties. This practice aligns with best management practices in aggregate handling and ensures that the material used in construction meets specified requirements for gradation and quality.

Sampling uniformly from all areas of a stockpile is crucial for applications in construction and engineering, where consistent performance of the materials is essential for the integrity of the final product.
