Special Issue Information

Dear Colleagues,

An upcoming Special Issue on “Sustainable Road Construction” aims to publish the latest, high-quality research or review papers in the field of road construction with a particular emphasis on sustainability.

From an environmental point of view, the road construction process generates four serious environmental problems: natural resource depletion, energy consumption, waste accumulation and environmental degradation. To address these problems and shift the road construction process towards sustainability, the road construction sector has undertaken the task of including the sustainable management of natural resources and new environmentally friendly technologies in the traditional road construction process. The sustainable management of natural resources promotes the application of recycling technologies, utilization of waste materials and by-products, conservation of natural resources, reduction in quantities of disposed materials, reduction in energy consumption and reduction in environmental pollution. New environmentally friendly technologies contribute to sustainable road construction by enhancing cost-effectiveness, improving process efficiency, and creating processes, products or services that are environmentally beneficial.

Today's road construction sector must respect the concept of sustainability, capable of meeting needs without compromising the ability of future generations to meet their own while integrating economic, social, and environmental aspects.

The essential purpose of this Special Issue is to collect papers dealing with this important, omnipresent topic, considering all aspects of sustainable road construction solutions, currently used or to be implemented to achieve the engineering goals for which the roads were constructed, such as to reduce the consumption of energy and virgin materials, preserve and restore surrounding ecosystems, implement environmental and economy friendly maintenance, introduce recycle materials, waste and by-products from a different industrial process, reduce the air, noise and lighting pollution as well as heat island effects.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The last decade has witnessed increased attention toward products, services, and works with reduced environmental impacts. In the field of road construction, the use of alternative materials, wastes, or by-products obtained from industries is attracting considerable interest. The Life Cycle Assessment (LCA) is a powerful project-level tool that allows the assessment of the environmental impacts of a road infrastructure, from raw materials production to end of life phase. In this study, the environmental impacts (in terms of global warming potential-GWP) of an embankment construction project are investigated by a cradle-to-gate approach. The analysis focuses on all the processes involved in the construction of an embankment section, from the base to the preparation of the pavement formation level. The results are provided for two different road types and two different stabilization methods, including the use of lignin and lime. All processes that contribute towards global warming are investigated and described in detail. The most important finding of the LCA, in terms of GWP, is that the production of materials is the phase that contributes the significant share of the total environmental impact (more than 90%) for all scenarios. The lowest production-related emissions can be recorded for the scenarios involving lignin treatment for the stabilization of the embankment body. Furthermore, the percentage increase in GWP ranges between 51% and 39% for transportation activities and 10–11% for construction activities, comparing the scenarios including lime stabilization with the scenarios involving lignin treatment.

The use of reclaimed asphalt pavement (RAP) is necessary for sustainable and cost-effective road infrastructure construction. This research investigates the effect of the area of weak zones (WZ) on the resilient modulus (MRT) of mixtures of fresh asphalt with 20% RAP. Experimentation on fresh asphalt–RAP mixtures comprising Superpave (SP-A, SP-B) and Asphalt Institute (MS-2) gradations with 20/30, 40/50, 60/70 and 80/100 penetration grade binders was carried out. WZ were determined based on the analysis of magnified digital images of asphalt specimens obtained using optical microscopy. This study demonstrates that the 20/30 grade binder caused an increase in the MRT at 25 °C up to 1.8, 2.9 and 9.2 times for a 0.1 s load duration, and 2.4, 3.0 and 9.7 times for a 0.3 s load duration. In contrast, improvement at 40 °C was observed to be up to 1.9, 3.1 and 9.7 times for a 0.1 s load duration, and 1.9, 3.0 and 12.4 times for a 0.3 s load duration in comparison with 40/50, 60/70 and 80/100 grade binders, respectively. Experimental data were validated by factorial analysis. Power trendline equations were also developed between MRT and WZ to explain the effect of gravel particle orientation on the sustainable resilience of surface course mixtures. Full article
