“…For example, Widman (1998) confined scope by focusing on the substructure with pilings and the superstructure with railings and the deck surface. Bouhaya et al (2009) excluded the foundation and the superstructure equipment of barriers, sidewalk, and pavement in the analysis. The result would have been different if the scope is focusing on the whole bridge.…”

“…He also highlighted that the importance of the time horizon during the long life span of the bridge, a good LCA should quantify the widest range of environmental outputs instead of only greenhouse gases. Bouhaya et al (2009) performed a life cycle assessment for assessing the energy release and greenhouse gas emissions of a roadway bridge. The foundation and the superstructure equipment of barriers, sidewalk, and pavement were excluded from the functional unit.…”

ABSTRACT:Currently the whole world is confronted with great challenges related with environmental issues. As a fundamental infrastructure in transport networks, railway bridges are responsible for numerous material and energy consumption through their life cycle, which in turn leads to significant environmental burdens. However, present management of railway bridge infrastructures is mainly focused on the technical and financial aspects, while the environmental assessment is rarely integrated. Life cycle assessment (LCA) is deemed as a systematic method for assessing also the environmental impact of products and systems, but its application in railway bridge infrastructures is rare. Very limited literature and research studies are available in this area. In order to incorporate the implementation of LCA into railway bridges and set new design criteria, this article performs an elaborate literature survey and presents current developments regarding the LCA implementation for railway bridges. Several critical issues are discussed and highlighted in detail. The discussion is focused on the methodology, practical operational issues and data collections. Finally, a systematic LCA framework for quantifying environmental impacts for railway bridges is introduced and interpreted as a potential guideline.

“…There are many works in which the environmental impact assessment is carried out taking into account a small number of indicators, of which the CO 2 emissions are the most popular [35,36]. Despite the importance of the emission of CO 2 , a complete impact assessment must consider a set of indicators that represent a complete environmental profile.…”

Abstract:The construction sector is one of the most active sectors, with a high economic, environmental and social impact. For this reason, the sustainable design of structures and buildings is a trend that must be followed. Bridges are one of the most important structures in the construction sector, as their construction and maintenance are crucial to achieve and retain the best transport between different places. Nowadays, the choice of bridge design depends on the initial economic criterion but other criteria should be considered to assess the environmental and social aspects. Furthermore, for a correct choice, the influence of these criteria during the bridge life-cycle must be taken into account. This study aims to analyse the life-cycle environmental impact of efficient structures from the economic point of view. Life-cycle assessment process is used to obtain all the environmental information about bridges. In this paper, a prestressed concrete precast bridge is cost-optimized and afterwards, the life-cycle assessment is carried out to achieve the environmental information about the bridge.

“…Timber is a sustainable building material -a natural and renewable resource, whose production requires small amounts of non-renewable energy (Petersen and Solberg 2002;Falk 2009). Besides, timber is a carbon store that can decrease the environmental impact of construction, through its carbon sequestration mechanism, depending on its end-of-life treatment (Bouhaya et al 2009). …”

This review article presents a state-of-the-art survey on timber-concrete composite (TCC) bridges. It starts with a presentation of a sample of relevant TCC bridges, offering a global perspective on the use of this type of bridge. The number of TCC bridges has clearly increased in the past few years, and some of the reasons for this trend are explored. Next, an extensive literature review is presented regarding the most significant technological innovations and recent developments in the application of TCC structures to bridge construction. Firstly, the engineering specificities and the advantages of TCC bridge structural systems are enumerated. Afterwards, the importance of proper mechanical connection for optimal performance of TCC structures is explained, and a thorough description of the connection systems suitable for bridge construction is provided. Some research into the structural behavior of TCC bridges under service conditions is then presented and discussed. Finally, possible areas of future research regarding the development of TCC bridges are suggested.
