“…The primary data and some other relevant inputs and outputs connected with the asphalt production, such as energy and heating consumption were obtained from the literature (Gschösser, 2011;Gschösser et al, 2012;Lima, Hajibabaei, et al, 2020). The asphalt mixtures were designed in the laboratory and the recipes were obtained through tests conducted in accordance with the EN 12697-30 and EN 12687-35 standards.…”

Several studies evaluated the feasibility of using residues to compose asphalt mixtures. However, the demand for treatments are often neglected in determining the environmental impacts. This study aims to elucidate the decision-making process over the application of residues (e.g., red mud and fly ash) to produce asphalt mixtures. For comparison purposes, limestone and dolomite are used as reference fillers. The cradle-to-gate approach is applied within three scenarios. In the first scenario, the treatment of the residues is included in the modelling, the second excludes treatment, and the third scenario evaluates the environmental impacts of the residues deposited in landfills. To perform the analysis, indicators such as Global Warming Potential, Acidification, and Cumulative Energy Demand are applied. The results show that the treatment provided to the residues strongly influences the environmental impacts of the production of asphalt mixtures and may be crucial to define the feasibility of the residues application.

With the spread of the notion of sustainability, evaluating alternative roadway design options in terms of economic factors solely has become insufficient, and a need has risen to incorporate environmental and social dimensions. In response to this need, life-cycle evaluation (LCE), which consists of assessing the impacts of certain product/project from cradle to grave, has gained popularity among the pavement community. In its broad sense, LCE encompasses three main evaluation methods that are discussed thoroughly in this paper: life-cycle cost analysis (LCCA), life-cycle assessment (LCA), and social life-cycle assessment (SLCA). An integration of all three LCE methods is known as life-cycle sustainability assessment (LCSA). This paper presents a review of the evolution of LCE through each of these evaluation methods with a focus on pavement methods, applications, and tools. The authors attempt to identify gaps in research and practice of pavement LCE, and to propose enhancements. Incorporating the social dimension of sustainability in pavement LCE and relying on accurate performance prediction and traffic characterization are examples of such improvements. The authors also give suggestions for LCSA scope definition and multi-objective decision making. The paper concludes with recommendations for future research and applications.

“…Thereby, the minimum (variant 1), the maximum (variant 2) and the aspired lifetimes (variant 3) of the different pavement layers were identified, and based on these lifetimes, the three comparable maintenance strategies for each pavement type were compiled ( Table 3). 20 .…”

The subject of this paper is an environmental life cycle assessment (LCA) and life cycle cost analysis (LCCA) of processes needed to construct and maintain representative Swiss asphalt, concrete, and composite pavements (including subbase layers) applicable for the Swiss national road network over a period of 75 years. The environmental indicators analyzed are the global warming potential indicator, the nonrenewable cumulative energy demand, and the Swiss ecological scarcity indicator. Processes of the use phase of the road (fuel consumption, noise, etc.) have been evaluated qualitatively based on intensive research. The study shows that the global warming potential of concrete and asphalt pavements equilibrates over the analysis period and that concrete pavements compared to asphalt and composite pavements offer advantages in regards to the nonrenewable cumulative energy demand, the ecological scarcity indicator, and life cycle costs. The qualitative evaluation of the processes of the use phase shows for example the positive qualities of concrete pavements regarding fuel consumption and permanent noise properties.
