Road transport is one of the main contributors to increasing greenhouse gas (GHG) emissions, consequently aggravating global warming, but it is also one of the sectors that most suffer from climate change, which causes extreme weather events. Thus, strategies, also called adaptation measures, have been discussed to minimize the impacts of climate change on transport systems and their infrastructure; however, a knowledge gap is evident in the literature. Therefore, this article develops a systematic review with a bibliometric approach, still scarce in the literature, in renowned databases, focusing on studies developed on adaptation measures for road infrastructure. The results show that, since the development of the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), an increasing amount of studies on the theme have been published in recognized journals such as Science of the Total Environment, Energy and Buildings and Urban Climate, analyzing climate threats such as intense precipitations and high temperatures that have led to biophysical impacts such as flooding and urban heat island. In addition, for each type of adverse weather condition, many impacts on road infrastructure can be listed, as well as ways to detect these impacts, and adaptation measures that can be used to minimize these problems.

The transport sector is responsible for several environmental impacts, including contributions to climate change through greenhouse gas emissions and depleting natural resources. A strategy to reduce these issues goes towards the application of a circular economy, a concept that offers a response to increasing concerns about resource scarcity and the associated impacts from their use. Thus, this paper aims to fill a gap in the literature that consists of the scarcity of studies that consider the circular economy application on a micro, meso, and macro level in road transport, including all stages as well as the 7 Rs of the reverse cycle. Therefore, an approach is presented to meet road transport needs, highlighting best practices obtained through a literature review, to promote climate change mitigation and resource depletion. Qualitative data were presented for each circular economy stage with 46 best practices identified, providing invaluable guidance to transport decision-makers. Thus, public policies focusing on all of the CE stages should be taken into consideration, not only those responsible for closing the cycle, such as waste and recycling or disposal and treatment.
