Production, Application and Properties of Bitumen (2nd Edition)

Dear Colleagues,

Bitumen is one of the oldest binders used in road construction. This naturally occurring material found in deposits, such as bitumen lakes or bituminous rocks, has been used by humans for thousands of years. The progress of human civilization, advancements in technology, and the development of the automobile industry have increased the demand for better, more durable roads. Thus, the production of refined bitumen from heavy crude oil has surpassed the use of natural bitumen. This has led to new solutions in binder design. These include modifications of its properties with the addition of natural bitumen or the use of various chemical compounds, predominantly polymers, for improved viscoelastic performance. Cold in-place recycling represented a step toward the wider use of bitumen emulsion. However, the breakthrough in the development of bitumen technology was the implementation of low-temperature bituminous paving mixtures. Sustainable, eco-friendly warm mix asphalt (WMA) and half-warm mix asphalt (HWMA) technologies use synthetic waxes or surface-active agents (SAA) to lower bitumen viscosity. Water-foamed bitumen is the most recent innovative technique used in low-temperature mixtures. Systematic bitumen research is crucial for predicting bitumen characteristics and their effect on the performance of paving mixtures in pavement structures. This research, together with new laboratory testing technology and increased diagnostic requirements, will ensure the longer service life of pavements.

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. Materials 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 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.
