Special Issue Information
Dear Colleagues,
The Special Issue is focused on sustainable road pavements, which have been a critical concern for several decades. They were heralded by the appearance of “long-life pavements”, as opposed to “durable” pavements, which implied the concept of satisfactory pavement performance. Long-life properties are considered achievable by using sustainable and environment-friendly paving materials and corresponding paving technologies. Usually, these sustainable methods can be obtained in several ways: 1) Reducing the production of waste by using high-performance bituminous materials; although they have a higher initial pavement cost, they are cheaper and sustainable from the viewpoint of life-cycle assessment because they are able to avoid the costs of road maintenance works, the waste generated during maintenance and the resulted delays for road users, particularly in congested traffic conditions. 2) Reusing construction wastes (i.e., reclaimed asphalt pavement materials), especially in the case of incorporating bio-based rejuvenators, which are low in cost and essentially sustainable but associated with shorter service lifetime, and so studies must be conducted in order to improve their service performances. 3) Applying functional bituminous materials like self-healing asphalts, self-regulating-temperature asphalts etc., which open up novel ways to achieve sustainability and reduce greenhouse gas emissions. 4) Using various kinds of bio-based materials as construction materials, such as bio-oils, bio-wastes, bio-asphalts, etc. 5) Applying energy-saving technologies such as warm-mix or cold-mix technologies, preservative maintenance, micro-surfacing, fog seal etc. This Special Issue will provide a collection of noteworthy experimental and/or numerical investigations and case studies related to these sustainable bituminous materials and reduced greenhouse gas emission paving technologies.
Topics of interest include:
- Preparation and characterization of sustainable bituminous materials;
- Thermorheological behaviors of sustainable bituminous materials;
- Energy-saving paving technologies;
- Carbon footprint analysis and life-cycle assessment studies.
In this Special Issue, original research articles and reviews are welcome.
We look forward to receiving your contributions.

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.
