STUDI KUAT TEKAN TANAH PASIR BERLEMPUNG YANG DISTABILISASI MENGGUNAKAN ABU GUNUNG MERAPI
ABSTRACT: The tested soil
sample in this research is sandy clay soil. The variations of procentage are
5%,10%, 15%, and 20%. Each of samples are cured in 14 days. Based on the
physical soil propertiesinvestigation, AASHTO classified the soil sample into
A-2-6 group (sandy clay soil), while USCSclassified the soil sample as soil
with rough granules into SC group.The results of the research in the laboratory
showed that the additive material using Merapi vol -canic ash could improve the
physical and mechanical properties of organic clay soil. In the physi-cal test
such as unit weight and Atterberg limit tests, the values decreased after it,
while the me-chanical test of Merapi ash sample showed it could improve the
value of unconfined compressionstrength soil. Based on the result of unconfined
compression stregth test, soil which is stabilizedusing the ash of Mount Merapi
increase until the optimum ash content about 20%.
