Abstract

In the execution of construction, the selection, process, and results of compaction are very concerned. These three things greatly affect the energy and costs used. Characteristics of density, strength, compressibility, and permeability are strongly influenced by the content of coarse grains and fine grains in it. The presence of fine grain content in the material will cause the presence of minerals which results in an increase in water absorption. While coarse grains in the material will tend to have a higher density. This study examines compaction characteristics from the influence of fine grain content from a mixture of residual material. The material used came from West Java, namely red soil from Lagadar and sand from Padalarang. This study uses seven different percentages of fine grains,that is 10%, 20%, 30%, 40%, 50%, 70%, and 100%. Laboratory compaction testing using Standard Proctor Compaction Test (ASTM D 698-91). Based on the results of compacting test obtained the maximum density (MDD) from fine grain material content of 10% to 100% are 1.53, 1.49, 1.47, 1.42, 1.39, 1.38, and 1.36 gr / cm3, while the optimum water is 19%, 20%, 22.5%, 26%, 31%, 32%, and 34%. From these results it can be seen that a percentage increase in fine grains will increase the optimum moisture content (OMC) and reduce the maximum density value (MDD). The percentage of fine grains is 10%, 20%, and 30% resulting in MDD values that tend to be the same, with a difference of 1.3%. Based on these results, material with fine grain content of 10% to 30% is recommended for material embankment.
