STUDI DAYA DUKUNG TANAH LEMPUNG LUNAK YANG DISTABILISASI MENGGUNAKAN TX 300 SEBAGAI LAPISAN SUBGRADE
ABSTRACT: Road construction
requires good subgrade to put down parts of road pavement that it put downabove
subgrade. However, soil can make problem if it has bad characteristic and loss,
forexample high plasticity, low shear strenght, compression or volume change
and large potensial ofswelling-shrinking. To overcome these, it is needed an
improvement of soil that is called with soilstabilization use additive and one
of them use TX 300 that come from America.Results of laboratory research show
stabilization materials use TX 300 as stabilizing agent canimprove the physical
and mechanical properties of soft clay soil. On physical test such as
specificgravity and plasticity index, it decreased after stabilization. While
the mechanical testing, usage ofTX 300 is effective enough in increasing the bearing
capacity of soft clay soil. From the testresults of laboratorys CBR, soil that
has been stabilized with a mixture of the TX 300 can be usedas a subgrade for
road construction due to CBRs value 6 %.
