These new composite geomaterials have some problems, such as increased construction time, cost,<br>and adverse impacts on the environment. As a result, conventional geomaterials are usually chosen over<br>composite geomaterials in Japan. However, there are few researches that analyzed the environmental impacts<br>(for example, CO2, NOx, and SOx emissions as well as total life-cycle cost) of traditional and composite<br>geomaterials quantitatively from the perspective of LCA (life cycle assessment). Therefore, the purpose of this<br>research is to apply a LCA to estimate the total emissions of CO2, NOx, and SOx as well as the total life cycle<br>costs of three embankments—one constructed by the conventional method (cut and fill), one with lightweight<br>geomaterial mixed with expanded polystyrene beads, and one by the expanded polystyrol construction method.<br>All three embankments are located on a mountain road in Japan.<br><br></p> ER -
