Collapsible soils, such as loess, present critical challenges in geotechnical engineering due to their tendency to undergo significant settlement upon wetting or loading. With the increasing demand for land development through engineered fills, ensuring adequate strength and stability during soil compaction has become essential. Accurate assessment of compaction, often represented by the compactness of the soil, is a key parameter in quality control. This study investigates the transfer and distribution of compaction energy in collapsible soils through laboratory Proctor compaction tests. Loess soil specimens were tested at moisture contents ranging from dry of optimum to wet of optimum, under varying compaction energy levels. The applied hammer impact force (E₀) and the resulting soil bottom force (E) were recorded using an impact load cell placed at the base of the compaction mould. The energy consumption ratio (E/E₀) was calculated and compared with the conventional compaction curve. Results indicate that the variation of energy consumption ratio with moisture content closely mirrors the compaction behaviour of the soil. Thus, the E/E₀ ratio serves as a viable parameter for assessing compaction characteristics in terms of energy, offering a quantitative approach for compaction quality control in collapsible soils.
