Special Issue Information
Dear Colleagues,
A themed Special Issue of Sustainability on Soils Stabilization and Sustainability Challenges is planned for 2021.
Soil stabilization has been commonly used to improve the mechanical and chemical properties of problematic soils especially for highway, airport runway, and rail track construction. Implementing this method may enhance the soil bearing capacity, reduce soil settlement and permeability, and control the shrinking/swelling ratio. Cement- and lime-based stabilizers are the most popular stabilizer agents used widely in this soil stabilization technique. However, due to the negative environmental impacts of cement and lime production and to gain more awareness of the sustainability issues, the use of alternative cementitious binders obtained from recycled waste byproducts is a preferred approach. Today, material such as fly ash (FA), bottom ash (BA), rice husk ash (RHA), palm oil fly ash (POFA), biomass ash, calcium carbide residue (CCR), and other recycled waste byproducts have been widely applied in practical infrastructure projects and extensively explored.
In addition, less attention has been paid to the impact of wetting/drying cycles on engineering behavior for stabilized soil. This may contribute to the poorer performance of stabilized soil over the service life of the stabilized earth structure. Therefore, the effect of climate change on the long-term characteristics of stabilized soil should be investigated.
The purpose of this Special Issue of Sustainability is to promote outstanding research in various aspects of soil stabilization applications and the current challenges, especially in sustainability issues. Potential topics include but are not limited to the following:
- Review of soil stabilization issues and their sustainability challenges;
- Development of novel stabilization agents;
- Application of recycled waste byproducts in soil stabilization;
- Technical and economic evaluation of soil stabilization;
- Life cycle assessment of stabilized soil under long-term climatic conditions.

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.
