Civil Engineering life cycle assessment lca life cycle costing lcc geosynthetics retaining wall geotextile gabion mechanically stabilized earth mse The purpose of this thesis is to determine the best outcome in a systems approach analyzing cost, emissions, and lifetime of traditional soil remediation with geosynthetic materials. The soil remediation systems will be analyzed by conducting a life cycle assessment (LCA) and a life cycle cost (LCC) analysis on the materials used within the system. This study will not include a life cycle impact assessment because this thesis is a preliminary LCA.A retaining wall case study is an excellent lens for examining traditional materials and geosynthetics. The retaining wall was selected due to its relevance and frequency within geotechnical applications, and provides an avenue to evaluate the life cycle, cost effectiveness, and utility of geosynthetics. The four design alternatives include concrete gravity walls, mechanically stabilized earth walls, geotextile wrap-around walls, and gabion walls. The LCI will be analyzed using a comprehensive publicly available database. As diverse as different materials are, geosynthetic properties including density, roll length, etc. will be determined using required design parameters, considering the median values in order to represent an “average” product.While traditional materials (i.e., soil and stone) tend to be the most massive element of the retaining wall and therefore contain a substantial amount of embodied carbon, the amount of embodied carbon or embodied energy within the geosynthetic is not insignificant. Three walls showed a greater contribution from the man-made materials toward the total embodied carbon. However, the greatest contribution toward embodied energy came from the man-made materials for both the gravity retaining wall and the geotextile wrap-around wall. The LCC was performed to determine the true cost of construction of the retaining wall over its life cycle. In observing the results from the LCI as well as the total cost, it can be seen that the geotextile wrap-around wall outperforms the other wall alternatives in every category. 2015 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1430346779 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1430346779 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
