In arid and semi-arid regions, compaction is challenged by water scarcity and high transport costs. One proposed solution is to increase the compaction energy. However, this strategy can be replaced by the addition of coarse materials to increase soil compaction where possible. This study analyses and compares the effectiveness of increasing compaction energy and adding coarse materials, such as gravel, to fine-grained soils. The research includes compacting soils at both optimum and low water content levels to assess their effect on the maximum dry density and bearing capacity of the soil under investigation.
