Abstract :
The stability of embankment construction on clay soil is influenced by several factors such as embankment and subgrade parameters, embankment dimensions and subgrade depth. But not infrequently clay which is often found on subgrade to build roads or other building construction is not very supportive to withstand the construction load. Analysis will be carried out with the GEO5 program by making variations on the parameters of embankment and subgrade and the slope. The soil variations to be analyzed are native soil, initial soil (common soil parameters as a comparison), stabilized soil 5% glass powder + 1% plastic chopped, stabilized soil 10% glass powder + 1% plastic chopped, and 15% stabilized soil glass powder + 1% plastic chopped. The results of the analysis that the minimum safety factor is found in the original soil as native soil as subgrade and initial soil as embankment is 2.51 on the slope of 1: 1 and 2.61 on the slope of 1: 1.5, while the maximum safety factor is found in stabilized soil 10% glass powder + 1% chopped plastic as subgrade and stabilized soil 10% glass powder + 1% chopped plastic as heap 8.87 at slope 1: 1 and 9.18 at slope 1: 1.5.
