Subgrade strength is a major factor in pavement design, construction, and performance. The subgrade for road pavement construction can be in the form of local soil (in-situ) which is stripped or cleaned after it is compacted, or it can be filled soil compacted according to the maximum density. Efforts are made to increase the bearing capacity of the subgrade or subgrade on soft soil, one of which is to physically improve the soil, meaning by replacing it with soil that has a good or adequate bearing capacity. The purpose of the study was to determine the characteristics of the embankment soil as a road subgrade. The method used is testing the physical and mechanical properties of the soil. Soil samples were taken from Kampar and Duri quarry. The results of the research on soil classification for the Kampar quarry, type ML, and the Duri quarry type CL. CBR value of Kampar quarry soil 23% and Duri 16.80%. Conclusion the characteristics of the embankment soil should not contain organic and high plasticity. For CBR value > 10% based on the specification of Bina Marga 2018 Revision 2.
