Maintaining stockpiles of aggregate in a well-drained condition is crucial primarily to minimize free water content. When aggregates are allowed to accumulate moisture, it can lead to several issues, including improper mixing ratios when concrete is produced and potential degradation of the material itself. Excessive moisture can alter the physical properties of the aggregates, leading to inconsistent batches. Additionally, when aggregates retain water, it can negatively affect the integrity and strength of the concrete produced, as the water ratio in the mix is critical to achieving desired characteristics in the final product. Therefore, ensuring that stockpiles are well-drained helps maintain the quality and performance of the concrete mix by keeping the aggregate moisture content at optimal levels.
