This material is already used in numerous construction projects due to its light characteristics. Lightweight Modular Block or LMB is a type of EPSCS composed of dredged Soil, cement, and Expanded Polystyrene (EPS). The amount of cement composition are 3%, 5%,7% and 9%. Meanwhile, Expanded Polystyrene (EPS) are 0.5% and 0.75%. This paper aims to briefly explain the performance of LMB as road foundation materials, such as subbase and base, through CBR laboratory tests. Based on the data, adding EPS can reduce density by 18% - 29% depending on the chosen mixture. Whereas adding more cement tends to increase the CBR value. All the test results will be analyzed and compared to SNI 03-3438-1994 for its qualification as a road foundation layer. ## Keywords - Subbase - Expanded polystyrene - Cement - Foundation (evidence) - Asphalt - Environmental science - Geotechnical engineering - Modular design - Base course - Engineering - Materials science - Computer science - Composite material - Mathematics - Topological space - Extension topology - Discrete mathematics - General topology - History - Archaeology - Operating system --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
