Advances in Renewable Asphalt Pavement Materials

Dear Colleagues,

Asphalt pavements constitute one of the most common infrastructures across the world. Globally, pavement construction and maintenance consume a remarkable amount of asphalt mixtures. At present, asphalt mixture productions are progressively moving towards "green" and more sustainable solutions, aiming to minimize environmental impact and energy consumption. As a result, renewable asphalt pavement materials have gained the increasing attention of pavement researchers and engineers.

Several technologies have been used in the pavement industry to produce renewable materials. One common practice is to recycle the reclaimed asphalt pavements (RAPs) in producing materials in order to preserve new aggregate, filler, and asphalt binder. In addition to RAPs, wasted tire rubber and wasted plastic have also been used to form the pavement materials, resulting in a green and sustainable recycling process. Another frequently used technique is to use the renewable bio-binder in pavement materials to replace the non-renewable asphalt bitumen. Applications of the above technologies help to maximize the use of recycled materials, industrial by-products, and wastes in pavement materials and generate a more renewable asphalt pavement.

This Special Issue of "Advances in renewable asphalt pavement materials" covers general topics on renewable asphalt pavement material design and production based on waste material recycling and renewable material additive. This Special Issue will publish full research papers and reviews. Areas to be covered in this research topic may include, but are not limited to, the following:

• Advances in renewable pavement materials produced with RAPs;
• The application of bio-binder in pavement materials to replace asphalt bitumen;
• Recycling tire rubber in pavement materials;
• Recycling waste plastic in pavement materials;
• Pavement construction technology with renewable materials;
• Life cycle assessment on renewable pavement materials.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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.
