Pengaruh Penambahan Pasir Terhadap Tingkat Kepadatan dan Daya Dukung Tanah Lempung Organik

Abstract

The problem of density level and bearing capacity of soil is one of things that really need to
considered in the planning and construction work of a civilian building . This is because the land
in question serves as a medium that holds the load or the action of a construction that is built on it
. Stabilization using sand material is one way to meet the needs of the required strength . Changes
in weather and temperature in the field are factors that makes the soil unstable .
The type of soil is organic clay stabilized from the Gedong Pasir village, Jabung District, East
Lampung District. This research was conducted by using a mixture of sand with variations mixture
of 5 %, 10 % and 15 %. After the CBR testing, Density, Atterberg Limits and Specific Gravity for
each sample.
The more variations of a mixture of sand were added resulting in declining water levels that would
make the value of the soil carrying capacity increases, the value of density and plastic limit
increased, while the value of the liquid limit and plasticity index decrease.
Keywords: sand, organic clay, bearing capacity
