PENGARUH FRAKSI PASIR DALAM CAMPURAN TANAH LEMPUNG TERHADAP NILAI CBR DAN INDEKS PLASTISITAS UNTUK MENINGKATKAN DAYA DUKUNG TANAH DASAR
ABSTRACT: CBR-value is used as
an index of soil strength and bearing capacity. This value is broadly used and
applied in design of the base and the sub-base material for pavement. Sand
stabilized soils are often used for the construction of these pavement layers
and also for embankments. CBR-value is a familiar indicator test used to
evaluate the strength of soils for these applications. CBR-test was conducted
to characterize the strength and the bearing capacity of the studied soils and
their mixtures with sand. CBR-values of the diference soils, compacted at
optimum water content, Atterbeg limit are given in this report. All the
specimens were prepared using a standard proctor test.
The results of the research will be made in the form of a graph on the
relationship between the value of CBR to the liquid limit., LL, maximum dry
density. The results also will display the graphic relationship between the
plasticity index with content of sand fraction and clay fraction.
The test results show that the Atterberg limits that a percentage of the
original soil and addition of sand. ff (loose soil). The results showed that
Relationships LL CBR value and the fraction of sand fraction that the lower the
value of LL will increase the value CBRnya. The results showed that the content
of the sand can increase the value CBRn. CBR value is highest at 71.11% sand
content.
