Soil is one of the construction materials in civil works. Soft soil that has low bearing capacity becomes a problem in the construction process. To support the construction process, stable soil conditions are needed. The subgrade is the lowest layer of soil that serves as a place for laying the pavement layer and supports the road pavement construction above it. By stabilizing the soil, soil quality will increase. A more stable soil layer makes it able to distribute the load much better. The addition of emulsified asphalt and tailings to soft soil is intended to stabilize or improve the soil. One of the parameters to determine whether the bearing capacity of the soil is good or not is by knowing the CBR value. This study aims to analyze the change in CBR value with the addition of emulsified asphalt and tailings. In this study, the percentage of 8% emulsified asphalt and 5%, 6% and 7% tailings with curing of 0, 7, and 14 days were used. The tests in this study included soil physical properties, Compaction, Atterberg limit and CBR testing without immersion. The results showed that the use of emulsified asphalt and tailing increased the maximum dry density and reduced the optimum water content. It can reduce the Plasticity Index by 76.00% from soft soils. The CBR results show the optimum value of stabilization on a mixture of 8% emulsified asphalt and 6% tailings with a maximum dry of 1.67 gr/cm3, the optimum moisture content is 25.13%, and the CBR value is 7.10% with a curing time of 7 days. It can be concluded that the use of emulsified asphalt and tailings with an effective composition can be used as an alternative material to stabilize soft soil on road pavement structures.
