Download or read book Sustainability assessment of concrete bridge deck designs in coastal environments using neutrosophic criteria weights written by Ignacio J. Navarro and published by Infinite Study. This book was released on with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essential infrastructures such as bridges are designed to provide a long-lasting and intergenerational functionality. In those cases, sustainability becomes of paramount importance when the infrastructure is exposed to aggressive environments, which can jeopardise their durability and lead to significant maintenance demands. The assessment of sustainability is however often complex and uncertain. The present study assesses the sustainability performance of 16 alternative designs of a concrete bridge deck in a coastal environment on the basis of a neutrosophic group analytic hierarchy process (AHP). The use of neutrosophic logic in the field of multi-criteria decision-making, as a generalisation of the widely used fuzzy logic, allows for a proper capture of the vagueness and uncertainties of the judgements emitted by the decision-makers. TOPSIS technique is then used to aggregate the different sustainability criteria. From the results, it is derived that only the simultaneous consideration of the economic, environmental and social life cycle impacts of a design shall lead to adequate sustainable designs. Choices made based on the optimality of a design in only some of the sustainability pillars will lead to erroneous conclusions. The use of concrete with silica fume has resulted in a sustainability performance of 46.3% better than conventional concrete designs.

Download or read book Pavement Roadway and Bridge Life Cycle Assessment 2020 written by John Harvey and published by CRC Press. This book was released on 2020-07-02 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.

This book was released on 2010 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Civil infrastructure systems such as highway transportation networks are tied up, directly or indirectly, with every country's economy in a major way. The state of nation's civil infrastructure has also significant impacts on the safety and quality of living. Among various infrastructure components, the highway bridges play a key role in a transportation network and huge money is spent every year to ensure their functionality. Over the time, highway bridges are aging, rapidly deteriorating, and becoming increasingly vulnerable to the catastrophic failure during probable natural or man-made hazards. In this study, the performance of reinforced concrete highway bridges, which form the majority of existing bridges in California, is evaluated during earthquake events while they have been continuously exposed to environmental stressors, such as attack of chloride ions. To assess the global structural degradation due to the deterioration mechanisms, an inventory of representative bridges of California with different structural attributes are studied. The extent of capacity loss is calculated using a finite difference procedure and the results are then utilized to find the life-cycle cost of bridges. The effects of deterioration processes on the functionality of the entire transportation network are also studied through the case-study analysis of the Los Angeles and Orange County highway transportation network. The change in the most important parameters associated with the network performance, such as total travel time, drivers delay, and traffic capacity, are thoroughly investigated following various bridge type-age scenarios. The inspection and maintenance costs of the whole system are then estimated using a multi-hazard framework to minimize the system costs while ensuring its safety.

This book was released on 2006-01-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
