Special Issue Information

Dear Colleagues,

Asphalt pavements are a commonly used technology in road construction. Roads currently being built or renovated will serve society for decades to come, so great care should be taken to use technologies that ensure appropriate durability and reliability. Efforts should be made to reduce the demand for natural raw materials and use materials from recycled building materials or waste materials from other industries.

Not only materials, but also technologies used during the production and installation of materials used in road construction layers, should aim to reduce the carbon footprint and reduce environmental pollution.

Proper assessment of the properties of reclaimed asphalt pavement and recycled binders is crucial to the design of mixtures containing a high percentage of recycled materials. There should be a discussion surrounding whether it is appropriate to test the recovered binder or whether the parameters should be verified on samples of asphalt mastic or even asphalt mortar.

Considering the life cycle of the surface, the use of long-lasting solutions, reducing the scope of maintenance procedures during operation and extending the periods between renovations, contributes to reducing environmental pollution.

I encourage you to start a scientific discussion on materials and technologies that will contribute to increasing the durability of pavement while increasing the use of recycled materials and reducing environmental pollution.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

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.

This article is a continuation of work on the use of plastic waste (such as PP, PS, LDPE, HDPE, and their mixtures) processed in the proprietary pyrolysis process as asphalt additives. The article carried out detailed tests of the mixes of selected additives with pen-graded bitumen 50/70, taking into account, among others, the influence of impurities and the ratio of PE to PP in the additives as well as short- (RTFOT) and long-term (RTFOT + PAV) ageing. An extensive research program was carried out, including functional and rheological tests in a wide range of temperatures. First, tests of stability and adhesion to various types of aggregates were carried out, demonstrating the usefulness of the proposed additives. Then, the elastic recovery and the impact of technological ageing on penetration, Fraass breaking temperature, and plasticity range were assessed. The same binder mixes were subjected to rheological tests in a wide range of technological and operational temperatures, assessing, among others, viscosity, the norm of the complex shear modulus, elastic recovery and compliance in the MSCR test, and stiffness in the bending beam rheometer. This entire class of tests was carried out for clean samples and those containing impurities, indicating their impact on individual material parameters. Full article
