Special Issue Information
Dear Colleagues,
Ultra-high-performance concrete (UHPC) has become very popular in the construction industry over the last two decades due to the enhanced mechanical and durability properties compared to conventional concretes. UHPC is a special type of concrete designed to exhibit excellent self-consolidating properties during the fresh stage, as well as very high compressive and sustained tensile strengths; the latter are achieved by using large amounts of fiber reinforcement. Many cement and concrete suppliers worldwide have now commercially available UHPC products that are increasingly being used in construction projects, mainly in the bridge sector. UHPC is a costly material because of the large amount of cementitious material, fiber reinforcement, and chemical admixtures. This is the reason why it has solely been used in small bridge elements (i.e., connections for prefabricated bridge elements), where the material volume required is small enough to justify the higher material costs. However, transportation agencies are now more receptive to its use, and more applications in both bridge and pavement sectors where larger UHPC volumes are required are being identified, such as bridge repair/rehabilitation and bridge deck overlays, to name just a few.
The practice of using higher quality infrastructure materials should translate into longer service lives, which results in lower maintenance needs and a lower frequency of replacement; both items that directly contribute to the sustainability of our world’s infrastructure. In addition, secondary benefits associated with high early age strength development of UHPC-class materials can have a lower impact on the traveling public, resulting in fewer delays and detours, and a lower environmental impact.
This Special Issue aims at including manuscripts that discuss the use of UHPC as an innovative material that can increase the service life of pavements and bridges, reduce delays to the traveling public, and decrease the environmental impact of pavements and bridges, thus promoting sustainability in the field of infrastructure construction.

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.
