“…Given financial limitations, agencies need to utilize systematic decision-making methodologies that offer insight into long-term economic viability. One such approach is the LCCA, which measures the economic risk when considering the sustainability of infrastructure projects [50,51]. However, the functional implementation of LCCA depends on a variety of factors such as the availability of supporting project documentation, the degradation insights into the state of the infrastructure, and the availability of guidance for calculating usage costs [40,52].…”

The comfort of human life depends on the quality, size, and reliability of the infrastructure projects. In the infrastructure systems, rapid growth is found, where the economic and sustainable impact has become a topic of significant concern for policies and government officials. To achieve con-straints of sustainable development, all the policies and actions over the infrastructure project's life cycle must be assessed. Decision-makers have adopted approaches for economic, social, and en-vironmental initiatives through Life Cycle Assessment (LCA) and Life Cycle Cost Analyses (LCCA) of infrastructure projects. The purpose of this review is to highlight the impact of per-forming LCA and LCCA in infrastructure projects. To achieve this goal, a systematic literature review methodology is adopted in which renowned databases, i.e., Web of Science, Science Direct, Emerald and Scopus were selected to extract the relevant literature. Using the PRISMA approach, 1251 publications were identified which were then filtered and 55 documents were included in the final review. In the extracted publications most, researchers were biased toward LCA and LCA individually, whereas few focused on integrated LCA and LCCA. The researchers assessed the costs and impact associated with the infrastructure project while there were less focused on the environmental cost. Besides this, techniques of economic, social, and environmental growth of infrastructure projects have been emphasized during the design phase because of substantial relations between infrastructure design and operation management. Moreover, a conceptual framework has been developed that will assist the decision-makers to consider the effects of LCA and LCCA on various aspects of the infrastructure project and how it impacts sustainability. In the last, a case study was performed to assess the developed framework with the incorporation of environmental impact cost.

“…The effects of traffic-induced vibrations on early-age mortar on the mechanical behavior of the repair material once it has hardened have not been studied. Currently, interest is increasing in asset management among transportation agencies around the world because infrastructure supports a nation's economic development, meets recreational and social needs, improves public health and safety, and promotes sustainability [2][3][4]. The rate of economic growth and development tends to slow when maintenance or retrofitting is required with the complete closure of a bridge [5].…”

A New Experimental Investigation for Improving Bridge Management Systems and Road Operation Sustainability

Generally, during maintenance operations on bridges and motorway viaducts, the circulation of vehicles is limited or suspended. This causes significant economic losses due to the increase in the costs of transport: delays, increased fuel consumption, higher emissions of pollutants into the atmosphere, increased risk of accidents, etc. However, few studies have analyzed the influence of bridge vibrations on the final mechanical properties of the cement mortar placing during ordinary bridge service. As such, interest is increasing in repair techniques that could achieve high structural performance without reducing road service levels. This paper provides the results obtained through an innovative laboratory trials campaign that evaluated the influence of vibrations on the mechanical properties of high-performance mortar used for repairing bridge decks. The results of 24 cubic and prismatic specimens showed the relationship between the traffic-induced vibrations and the mechanical characteristics of the studied mortar. The findings can be considered as the first methodologic step that is necessary to address further field studies, drawing a detailed link between the repair techniques and transportation user costs. Based on the obtained results, a synthetic bridge management system framework was developed that merges the road function into the structural issue with the goals of increasing the resilience of road networks and optimizing the maintenance resources budget.

“…Although such dysfunctionality does not always result in immediate collapse, time-based deterioration over a period of time may lead to bridge collapse. Thus, the natural disasters and time-based deterioration have drawn a good deal of attention of the bridge engineering and management community toward working on the concept of improvement of resilience (Giunta, 2017;Nezhad et al, 2022). Bridge resilience can be defined as a bridge ability to maintain its functionality, social, and economic value against the disaster; and to plan the recovery activities to regain its original functionality, social, and economic values within the shortest time (Patel et al, 2020).…”

The resilience of a bridge is computed using different quantitative and qualitative assessment methodologies. However, the resilience score obtained by these assessment approaches is insufficient for the decision-makers for setting a priority level for bridges in need of resilience improvement. To address this issue, the present study develops a methodology using the data envelopment analysis (DEA) approach. A total of 12 bridges are selected as the decision-making units in the DEA model. This study considers the variables such as age, area, design high flood level, and finish road level of the bridge as inputs, and bridge resilience index as the output variable. Based on these variables, three frameworks are developed to compute the efficiency of bridge resilience. A variable return to scale with the output-oriented formulation of DEA is selected to compute the efficiency of bridge resilience in all three frameworks. Thus, the proposed methodology enables bridge owners to set a priority level for bridges in need of resilience improvement based on the scores of the assessment methodology.
