One major issue in construction is settlement. Building any structure above compressible soils without proper consideration can lead to considerable damage and maintenance cost. Geofoam is a type of light-fill material in the lightest category. Since the 1970s, geofoam has been used worldwide to address settlement problems. Unfortunately, geofoam has not received much attention in Indonesia, mainly due to its cost compared to traditional fill. This paper covers the application of geofoam for road construction based on real soil conditions in Indonesia. From the analysis conducted, the use of geofoam reduces the compacted fill required by 40%. This saves not only construction time, but also carbon footprint of the road design. When the reduction of time by using geofoam is considered, geofoam becomes a feasible solution economically as well as environmentally.
