Sewer sedimentation in general cannot be used directly as construction materials due to the behaviour which is hard when it is dry and weak and soft when it is wet. Several engineering treatments that can be taken to improve the soil properties including adding a chemical stabilization using a mixture of materials. The stabilized soil samples came from Lam Glumpang Village, Ulee Kareng District, Banda Aceh. The purpose of this study was to obtain mechanical soil parameters before and after stabilization with lime. This research was conducted by mixing lime and lime soil with variations of 2%, 4%, 6%, and 8% of the dry weight of the soil. According to the AASHTO classification system, the soil is classified as A-4 (8) soil type, namely moderate to poor silt soil with an index group of 8, and according to the USCS classification system it is classified as an inorganic silt soil type with the symbol ML, namely silt soil with low plasticity. The results showed some good improvement in soil properties. In general, the addition of lime which has a good effect on sewer sedimentation soil in the mixture proportion of 6%. © Published under licence by IOP Publishing Ltd.
