Improving highway bases is the most crucial step that enhances pavements' performance and long-term durability. Lime Portland cement are commonly used in soil stabilization endeavors. Nevertheless, substantial carbon emissions associated with lime manufacturing have led to a growing interest researching environmentally friendly additives. Through standard proctor compaction tests one-dimensional consolidation tests, this research investigates behavior of fine-grained stabilized various content additives such as fly ash (FA), volcanic (VA), marble powder (MP), cement, their combination at different curing times (7, 14, 28, 90 days). Furthermore, evaluate characteristics materials, Atterberg limits, grain size distribution, X-ray fluorescence (XRF), scanning electron microscope (SEM), particle analysis (PSA), energy dispersive spectroscopy (EDS) been performed on selected materials. Various stabilizing agents effects behavior, maximum dry density (MDD) decreasing higher optimum moisture (OMC) values generally increasing, except for MP-stabilized samples. The results indicate addition FA, VA, MP, compressibility reductions. By raising proportion MP 20% extending duration days, compression index (C
