“…In order to make LCA conclusions more robust, it will be interesting to systematically implement different FUs, as a sensitivity analysis, as done by Loijos et al (2013), who implemented 12 different FUs to analyze 12 types of concrete pavements. The same approach was also followed by Wang et al (2012) and Santos et al (2014b).…”

“…In contrast, other studies have considered all the transportations during life cycle as a stand-alone phase in the life cycle(Zhang et al 2008, Cass and Mukherjee 2011, Kang et al 2014, Liu et al 2014, Santos et al 2014b). The M&R is also a of non-uniformity in pavements LCA.…”

“…However, very little is known about the environmental damages caused by the construction of these pavements [46]. Some studies have shown that the type of pavement can influence vehicle fuel consumption [47,48]. Taylor and Patten [48] have shown that Portland cement-based concrete pavements can decrease the amount of fuel consumed when compared to pavements constructed with hot-mix asphalt concrete (HMA).…”

The number of studies involving life cycle assessment has increased significantly in recent years. The life cycle assessment has been applied to assess the environmental performance of water infrastructures, including the environmental impacts associated with construction, maintenance and disposal, mainly evaluating the amount of greenhouse gas emissions, as well as the consumption of energy and natural resources. The objective of this paper is to present an overview of permeable pavements and show studies of life cycle assessment that compare the environmental performance of permeable pavements with traditional drainage systems. Although the studies found in the literature present an estimate of the sustainability of permeable pavements, the great heterogeneity in the evaluation methods and results is still notable. Therefore, it is necessary to homogenize the phases of goal and scope, inventory analysis, impact assessment and interpretation. It is also necessary to define the phases and processes of the evaluation, as well as the minimum amount of data to be considered in the modelling of life cycle assessment, in order to avoid heterogeneity in the functional units and other components. Thus, more consistent results will lead to a real evaluation of the environmental impacts caused by permeable pavements. Life cycle assessment studies are essential to guide planning and decision-making, leading to systems that consider increasing water resources and reducing natural disasters and environmental impacts.

“…In the last years, environmental sustainability has become an emerging field in the transportation industry Gransberg 2011, AzariJafari et al 2016), where terms such as green, sustainable development, environmental impact, energy efficiency, global warming, GHGs, and ecoefficiency are becoming more widely recognised (Chehovits andGalehouse 2010, Tighe andGransberg 2011). Previous literature has focused on how to quantify environmental impacts derived from pavement construction and M&R (Santero et al 2011, Santos et al 2014, AzariJafari et al 2016, Jiang and Wu 2019. However, when it comes to incorporate those efforts into the optimal planning of M&R strategies, much remains to be done to demystify its complexity at the decision-makers' (DMs') eyes (Gosse et al 2013, Bryce et al 2014, Torres-Machi et al 2014b.…”

Aged road pavements and insufficient maintenance budgets, along with increasing concerns over the environmental issues related to transportation have introduced additional challenges to highway agencies. Multiobjective optimisation techniques can be used to account for those multiple aspects in the design of maintenance and rehabilitation (M&R) strategies. Contrary to the single-objective optimisation problems where a single solution is optimal, the solution of multiobjective optimisation problems is a set of non-dominated solutions, often referred to as Pareto-optimal set. This set of optimal solutions represents the trade-off between the different and often conflicting objectives, and in many cases is comprised by a vast number of elements. This paper presents the development and application of a fuzzy logic expert system for selecting a single solution from the Pareto set obtained from the multiobjective optimisation of sustainable pavement M&R strategies. It provides decisionmakers with an easy and intuitive methodology for the selection of the most preferred solution according to sustainability criteria. The proposed system is applied to a case study from France. Posteriorly, different strategies reflecting the decision-maker's preferences towards economic and environmental objectives are analysed. Conclusions and recommendations for future improvements are derived from this application.
