Common problems that are often found on embankments are soil instability and low soil bearing capacity. To prevent landslides, consideration of the embankment stability and ways to improvement it is essential. This study investigates the use of quicklime as a stabilising material and a number of fill layers on the safety factor of the slope of the embankment in order to find the optimal combination. The type failure or deformation and extreme stresses that occurred in these soil embankments was also studied. Laboratory testing is used to determine soil properties. Three types of soil were analysed; subgrade, fill from original soil and fill from soil mixed with 15% quicklime. This quicklime mix was used as a 40 cm reinforcement layer on the slope surface of the embankment.
