The Proctor test is widely used in laboratories to determine the maximum dry unit weight and optimum moisture content of soils, but in real-world applications, static compaction methods are used. Consequently, this study explores the influence of static and dynamic laboratory compaction procedures on compaction characteristics and mechanical strength of fine-grained soil samples. Using the static compaction method, a set of parabolic compaction curves at various static pressures was generated, in contrast to the single compaction curve produced by the standard Proctor test. The study also sought to identify the equivalent static pressure required to achieve the maximum dry unit weight at optimum moisture content, corresponding to the standard Proctor test. Additionally, the study examined the mechanical strength of statically and dynamically compacted fine-grained soil by preparing specimens with optimum moisture and maximum dry unit weight, obtained from the standard Proctor test. The impact of clay minerals on compaction characteristics was also examined in these soil samples. The equivalent static pressure was found to be around 886 kN/m2, which agrees with the previous findings. Strength tests revealed that the unsoaked California Bearing Ratio (CBR) value of statically compacted soil specimens was higher than that of dynamically compacted soil specimens. The unconfined compressive strength (UCS) test showed a similar trend for some fine-grained samples, while others exhibited a reverse trend, potentially due to the development of suction phenomena in dynamically compacted soils, which may have temporarily increased UCS values. The study also conducted a microscopic analysis of post-compacted specimens and found a more homogeneous structure in statically compacted soil.
