METODA PERBAIKAN TANAH LUNAK PADA RUAS JALAN SEKINCAU - SUOH DI KABUPATEN LAMPUNG BARAT
ABSTRACT: Cement type used at
this research is PCC (Portland Composite Cement) which produced by PT.Indocement
Tunggal Prakarsa Tbk. Cement is an important material as construction principalcomponent.
There are many benefits that is taken from cement, as cement mixture on
building,even it can be used as soil stabilization agent, especially clay. This
research conducted to knowhow big swelling and swelling pressure on clay if it
was added by cements on PCC. Testconducted in three phases, (1). Physical
properties test of clay, and soil-cement PCC mixture, (2).Compaction test with
modified proctor method; and (3). Swelling and swelling pressure test with fold
loads 17,67 kg. Sample that will be tested is clay of Fila Tengah. Suwoh West
Lampung andclay that mixed cements of PCC with presentation 5%, 10%, and 15%.
Base on the result, the soilof Fila Tengah, Suwoh West Lampung is classified in
soft clay category (AASHTO and Unified classification). Another result obtained
explain that cements of PCC usage by the certain presentation can very affect
to clay swelling and swelling pressure. The swelling of clay that was reached
is 8,75 cm. Fifteen percent cements of PCC can be pressed decreasing became 6,5
cm. The swelling pressure of clay is 120,05 kPa. Fifteen percent cements of PCC
added is 70,03 kPa.Can be concluded that the best cement to clay stabilization
as mixture for clay is cements of PCC.
