Special Issue Information
Dear Colleagues,
Self-healing technology is a new field within material technology. It represents a revolution in materials engineering and is changing the way that materials behave. Incorporating self-healing technology into the road design process has the potential to transform the road construction and maintenance processes by increasing the life span of roads and eliminating the need for road maintenance. By decreasing the unnecessary premature ageing of the asphalt pavements self-healing asphalt will reduce the amount of natural resources used to maintain the road network, decrease the traffic disruption caused by road maintenance processes, decrease CO2 emissions during the road maintenance process and increase road safety. In addition to environmental savings, self-healing materials have the potential to deliver significant cost savings for road network maintenance.
Asphalt is already a self-healing material by nature. When subjected to rest periods, asphalt pavement has the potential to restore its stiffness and strength by closing the micro-cracks, which occur when the pavement is subjected to traffic loads.
Currently there are various research initiatives to improve the self-healing capacity of the asphalt. These technologies deal for instance with nanoparticles, induction heating and rejuvenation from outside or from inside by adding rejuvenator in capsules or fibres.
This Special Issue tries to attract articles in which these new technologies for improving self-healing of asphalt are described. The articles can focus on new concepts, experimental work, numerical modelling or applications of the new materials.

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. Applied Sciences 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.
