Human society is going through an interesting period in terms of the challenges it faces. The most interesting problems are environmental problems. In support of protection of the environment in which we live, we must find efficient and clean (ecological) solutions, at the same time, for the materials and technologies that are the basis of the goods production. In this context, the problem of means of transport, in general, and land road transport, in particular, will remain one whose solution will probably mark multiple stages in the attempt to abandon fossil fuels. Even if this problem will be solved, the travel routes – roadways – represent an additional challenge in terms of construction materials and technologies but also in terms of maintenance and rehabilitation technologies. In the context of Industry 4.0, the concerns in the field of road execution and repair are more and more obviously aimed at elements of the circular economy. Solutions are sought and experimented for: reuse of degraded asphalt material, incorporating reused/reusable materials into the asphalt mixtures and the implementation of ecological execution technologies. In this work, it is intended to carry out an analysis regarding the technical and technological solutions implemented or in the proposal/experiment stage that respond to the desired "Sustainable technologies for road maintenance and rehabilitation".

The credibility crisis of science is a growing topic of investigation. This study approaches the problem from the sustainability of the scholarly communication system by merging argumentation with information science.

Coding and content analysis drawing from a well-established textual argumentative tradition; a novel non-textual approach to complex communication and, an overlooked definition of sustainable information, were applied to 34 research works. The retrieval was carried out using Inciteful, a tool exploring literature networks. Additional information, such as keywords, mapping to Sustainable Development Goals (SDGs) and citations were acquired through the OpenAlex API. Operationalisation of concepts from the theoretical framework underpinned the selection and analysis of documents.

Scholars virtually involve peers, funding agencies, research councils, policymakers, experts, practitioners and representatives of the public in their formal written production. The described coalitions are occasional, while the needed ones are deep. Three forms of scholarly communication were found: traditional, dialogical and complex depending on the involved audiences. The sample tells us about the sustainability of the scientific communication system and the impact it may have on the public construction of imaginaries of science.

This investigation frames scholars, their products and societies as intertwined dialogical entities constantly communicating and impacting each other. Direct and indirect forms of scholarly communications are addressed too, showing how poor sustainability in these processes may entail a failure to reach different layers of societies.
