Abstract
In this study, compaction tests on three soil types (glacial aggregate mixture, amphibolite aggregate and sand-gravel mixture) were conducted in a full-scale plate compactor experiment under different frequency scenarios, specifically between 74 and 84 Hz. The experimental approach included measuring bulk density through photogrammetry and soil sampling at different layer depths. This methodology enabled the direct assessment of Relative Compaction (RC). Furthermore, soil stiffness was measured during compaction via a lightweight dynamic plate. Findings revealed that lower compaction frequencies generally resulted in denser compaction near the surface, while higher frequencies improved compaction at greater depths. Additionally, the study explored the relationship between dynamic modulus and RC. The study highlights the need for advanced, rapid compaction assessment methods, given the limitations of current techniques. The results indicate that within the analyzed range of compaction frequencies, both the dynamic modulus and RC requirements are achieved after the same number of compactor passes, regardless of the selected frequency scenario. Therefore, opting for a lower frequency can reduce fuel consumption and equipment wear while maintaining compaction objectives, leading to better overall efficiency.
期刊介绍:
Transportation Geotechnics is a journal dedicated to publishing high-quality, theoretical, and applied papers that cover all facets of geotechnics for transportation infrastructure such as roads, highways, railways, underground railways, airfields, and waterways. The journal places a special emphasis on case studies that present original work relevant to the sustainable construction of transportation infrastructure. The scope of topics it addresses includes the geotechnical properties of geomaterials for sustainable and rational design and construction, the behavior of compacted and stabilized geomaterials, the use of geosynthetics and reinforcement in constructed layers and interlayers, ground improvement and slope stability for transportation infrastructures, compaction technology and management, maintenance technology, the impact of climate, embankments for highways and high-speed trains, transition zones, dredging, underwater geotechnics for infrastructure purposes, and the modeling of multi-layered structures and supporting ground under dynamic and repeated loads.
