在散装固体领域，关于骨料库存中水分行为的处理知识可用于能耗方面的工艺优化。在沥青工业中，水分含量的增加导致能耗的显著增加。为了确定水分行为的特点，土壤水分运动理论和团聚体中的水分之间的相关性进行了研究。通过多孔底柱排水试验，发现理论和实践之间的相似性，这允许使用理论水文模型来确定和预测排水桩中的水分行为。研究了堆系统内工艺改变对能耗的影响，发现能耗显著降低。
In the field of bulk solids, handling knowledge on moisture behaviour in aggregate stockpiles can be useful for process optimisation in terms of energy consumption. In the asphalt industry, an increase in moisture content leads to a significant increase in energy consumption. To determine the characteristics of moisture behaviour, correlations are investigated between theory on soil–water movements and moisture in aggregates. With column drainage experiments with porous bottom, similarities between theory and practice are found. This allows the use of theoretical hydrologic models to determine and predict the moisture behaviour in drained piles. The effect of process alterations within the system of piles on energy consumption was investigated, and a significant reduction of energy consumption was found.
