Abstract
Soil conditions in the Gedebage area greatly affect the type of foundation used. The soil expansive is a type of soil that is soil properties such as high plasticity, high swelling, and large shrinkage potential. Soil improvement using mixed materials is mostly done to stabilize the soil. The stabilization used is emulsion asphalt which is locked of 8% and Lapindo mud variation of 3%, 6%, 9% and 12%. The results of physical and mechanical properties on soil material with stabilization of Lapindo mud and emulsion asphalt were obtained that the specific gravity increased by about 68%, with the density value (ωopt) of 16% and the dry weight content (d) of 6%. for the plastic index value on the original soil 47% while for mixture 1 is 15.72%, mixture 2 is 16.6%, mixture 3 is 9.5% and mixture 4 is 17.7%. CBR testing was taken forvariable 3 becauseit has the significant result of plasticity index which is is less than 10%. so that the results of this test were obtained by curing time of 14 days unsoaked by 8.1% for soaked by 4.6%. In the compressive strength testing, the more Lapindo mud mixture, the less compressive strength by.
