Comparison of the Number of Compactor Passes and the Constrained Modulus of a Compacted Volcanic Soil

Volcanic soil is often used as fill material in road embankment construction Java island-Indonesia. An understanding of the engineering properties compacted volcanic soils needed, especially during preliminary design phase and detailed embankment. Carrying out a field compaction trial test will significantly assist process construction. Selecting correct number passes from compactor can be obtained tests. Constrained modulus one that indicate stiffness This study aims to determine constrained compare it test. The this classified pumiceous tuff, which derived older rocks. highest value oedometer 10.38 MPa comes eight (8) times smooth drum roller conducted on
