Special Issue Information

Dear Colleagues,

Asphalt materials play a crucial role in pavement engineering. Pavement design has gradually evolved within the last century to ensure safe, comfortable, and efficient transportation.

Nowadays, advancements in pavement design, construction, and maintenance are being driven by emerging technologies and innovative materials that address current economic and environmental challenges and the desire for increased longevity.

Accordingly, we are launching this new Special Issue of Coatings that will collect original research articles and review papers.

Contributions will focus on the latest research achievements in the field of pavement engineering and forecast future research trends of pavement engineering. The scope of this Special Issue will serve as a forum for papers in the following areas:

  • Asphalt mixtures properties and design;
  • New methods of testing asphalt binders and mixtures;
  • Sustainable materials for road construction;
  • Effective pavement maintenance and preservation strategies;
  • Life cycle assessments for asphalt mixtures;
  • Smart and multifunctional pavement;
  • Any innovation aimed at enhancing the application of asphalt technology.

We look forward to receiving your contribution.

Dr. Ana María Rodríguez-Alloza
Guest Editor

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. Coatings is an international peer-reviewed open access monthly 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 2600 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.

Polymers are known to produce beneficial effects on asphalt mixtures, and lignin biopolymers could further improve them while contributing to sustainability and circularity. In this research, conventional asphalt emulsion was replaced with liquid waste containing lignin from the wood industry in half-warm mix asphalt (HWMA) at varying substitution levels of 0% (control), 5%, 10%, 15%, and 20%. Additionally, 100% reclaimed asphalt pavement (RAP) was used as aggregate. The impact of asphalt emulsion substitution on the mixtures’ adhesion, cohesion, and water resistance was analyzed. Indirect tensile strength tests evaluated the HWMA’s resistance to moisture damage and ductility. Rolling bottle and boiling water tests were conducted to assess the binder-aggregate affinity. Moreover, a Life Cycle Assessment (LCA) was performed to compare the environmental benefits of HWMA with those of Hot Mix Asphalt (HMA). The findings revealed that substituting asphalt emulsion with the waste lignin up to 15% enhances the mixture’s cohesion, while only substitutions up to 5% produce mixtures with enhanced water resistance. Environmental impacts were significantly reduced for all the HWMA studied, with the Global Warming Potential (GWP) showing up to 33.5% reduction compared to a conventional HMA. Full article
