Innovative design of soil pressure modeling test apparatus to determine the amount of soil compaction energy to dry density value

Abstract

A research in the laboratory about soil compaction is done using a hammer device, known as a standard proctor method and a modified proctor. Both methods use human strength to solidify the soil. This research is done well, because the compaction load and compactor height fall according to the research. Researchers tried to design and make a soil compactor with the same mold measure from standard proctor method but the compacting method use a hydraulic jack. So that the compressive strength and the energy can be measure to each layer. Thus the compacting energy can be measured and adjusted as needed. In addition, these results of compaction using a hydraulic jack will compare the soil compaction energy with standard proctor methods. The advantages of this new equipment can measure the compaction energy and dry density values. The research used modified press compactor test of 4 different pressures are 5 N/m2; 10 N/m2; 15 N/m2 and 20 N/m2. For every pressure conducted for 3 soil samples. After, the researcher will compare the soil compaction energy by standard proctor methode, new pressure test apparatus and with vehicle wheel pressure for soil compaction in the field.
