Surface Treatments and Coatings for Asphalt and Concrete—2nd Edition

Dear Colleagues,

Asphalt and recycled concrete are indispensable construction materials for modern buildings and infrastructure; they support many structures, from roads to bridges and buildings, due to their high strength, durability, and flexibility. However, the long-term exposure of these materials to the natural environment leads to surface degradation, such as aging and cracking in asphalt and the corrosion of recycled concrete. This affects the stability and lifespan of the overall structure. Therefore, the development of surface treatment and coating technologies is crucial for extending the service life of these materials. For asphalt, surface treatment technologies range from rejuvenators that restore flexibility to the addition of overlay materials that enhance waterproofing and abrasion resistance. For concrete, coatings are applied, such as epoxy resins, polyurethanes, and FRP (Fiber-Reinforced Polymer), which form a protective barrier that effectively isolates the intrusion of moisture, oxygen, and harmful chemicals, enhancing the durability of the structure. The selection and application of these coatings require consideration of material chemical compatibility, adhesion, weatherability, balance, ease of construction, and cost-effectiveness.

To further investigate this field, we plan to publish a Special Issue on surface treatment and coatings for asphalt and concrete. The aim is to bring together the latest findings from researchers and promote technological innovation.

The scope of this Special Issue includes, but is not limited to, the following topics:

• Interface performance of asphalt and recycled concrete;
• Latest advancements in corrosion-resistant coatings for materials;
• Development and application of high-performance and environmentally friendly coatings;
• EV durability and long-term performance prediction of coatings;
• Surface treatment strategies for special environments (e.g., extreme climates, cold regions, marine environments).

We express our sincere thanks to Dr. Long Liu from Anyang Institute of Technology, China, for his contribution to this Special Issue.

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-anonymized 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.
