Modification Compression Strength of Test Machine by Using Control System on Compaction Energy

Abstract Soil compaction for specific construction is determined soil density tests. Several methods have been developed by previous researches and the prominent method is soil density. Several types of soil compaction method in the field, namely compaction method using vibration machine, impact, and pressure. In laboratories, soil compaction test was performed by using a hammer which uses human strength to solidify soil. An experimental investigation was conducted to explore a new modification related to compression strength test machine with energy compaction control system control system the energy of compaction. Researchers tried to design and make a soil compactor with a different mould measures from the standard Proctor method to modified method. The special of this new tool is that it can measure the compaction energy from each layer and dry density values. This research used different pressures as much as 1.67 N/mm2 - 20 N/mm2, every load conducted for sandy clay and silt samples. The values of dry density obtained from this research were between 1.59 kN/m3 - 1.68 kN/m3 and the value is higher compared with the value obtained from experiments using the Standard Proctor system. Meanwhile, the soil compaction results in the laboratory by using a new modification compression strength test machine with energy compaction control system can be an option of heavy equipment which can be used in the field.
