Special Issue Information

Dear Colleagues,

In recent years, the value of using recycled materials in infrastructure construction has been recognized. These include the following, among others: recycled asphalt and concrete materials; fly ash and foundry sand; glass culets; crumb rubber; and recycled plastics. The recent emphasis on “low carbon materials” and “sustainable civil infrastructure” has generated additional impetus to increase their use and capture the added sustainability benefits.

The combined emphasis on performance and sustainability has generated new approaches and challenges currently explored by academia, industry, and the owners of civil infrastructure. Thus, the focus of this Special Issue on “The Impact of Recycled Materials on Infrastructure Performance and Sustainability” aims to include up-to-date research articles on recent studies that accomplish the following: (i) explore the impact of using recycled materials in civil infrastructure applications; (ii) utilize new design methods and a performance assessment of mixtures with recycled materials for highway and building construction applications; (iii) address the sustainability contributions of using recycling materials in terms of life cycle economic and environmental impact analysis, LCA, as well as “circular economy” principles; and (iv) develop “low carbon” construction materials considering “environmental product declarations”, EPDs, “cradle to gate” and “cradle to grave” life cycle assessment.

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 high demand for using recycled materials in roadways for sustainability has generated the need to develop new approaches to mix design in order to address and incorporate performance measures. In this regard, the mix design approach should identify methods to assess mixture performance, incorporating, for example, permanent deformation and fatigue cracking, to otherwise limiting volumetric analysis, as identified by the current Superpave approach used by many states. The objectives of this study were to develop such a methodology and identify threshold values for permanent deformation and fatigue cracking for the most common mixtures used in the state of Maryland. The performance testing results for fatigue cracking and permanent deformation are presented herein. Based on these results, initial threshold values were adopted. Furthermore, the experimentation included three distinct populations: plant mixtures; modified plant mixtures; and field mixtures (i.e., behind the paver). The results are presented herein along with relevant considerations about their potential use within quality assurance. The asphalt mixtures included in this study represent common or similar materials and mixtures often used in the northeast region. Thus, the suggested approach and overall testing results may be transferable elsewhere where similar materials and asphalt mixtures are used. Full article
