| dc.description.abstract | ABSTRACT
Soil compaction is widely applied and compaction tests play a crucial role in geotechnical
engineering. Compacted soils are inherently unsaturated, containing both air and water in their
voids. These tests aim to optimize the dry density of soils, which helps minimize future
settlement under load and decrease soil permeability. Achieving proper compaction is directly
linked to the durability and stability of various structures. Inadequate compaction often leads
to structural failures in roads and airfields, as well as damage due to foundation settlement.
Therefore, soil compaction is essential for any engineering projects involving earthworks.
The primary objective of this research is to enhance the existing knowledge of the soil
compaction process and the testing condition′s effect on automatic compaction results. This
study will introduce the design, development, and user manual and focus on the usefulness of
automatic compaction machines, which will replace traditional manual compaction because of
their many limitations. The research focuses on compaction tests conducted on various soils
with different plasticity characteristics combined with varying contents of water under diverse
testing conditions, such as compaction energy efforts that surpass the capabilities of manual
methods to explore the experimental behavior of soils, observe and evaluate the effect on
results in the experimental phase; and assessing the effectiveness of this model in predicting
soil compaction behavior.
The results indicate that the automatic compaction machine provides consistent and
reproducible compaction results, achieving higher dry densities and lower air void contents at
comparable energy levels. Additionally, the ability to control hammer velocity independently
from compaction energy highlights the machine′s versatility and efficiency.
This study concludes that the automatic compaction machine offers significant advantages
over traditional manual methods, including improved consistency, efficiency, and the potential
for higher compaction energy levels. These findings suggest that the automatic compaction
machine is a valuable tool for future geotechnical engineering applications, warranting further
research and development.
