Microwave heating of asphalt paving materials: Principles,
Microwave heating could contribute to the sustainability of several operations in the construction and maintenance of asphalt pavements. This paper aims at describing the current status of thisAbstract. Against a background of the immense solar radiation incident with available pavement surfaces, the opportunity for energy to be harvested from pavements is investigated. While the emphasis is on the harvesting of solar-derived heat energy, some attention is also paid to the collection of energy derived from displacement of theEnergy Harvesting from Pavements SpringerLink

Graphene related materials for thermal management
3.5.1. Graphene foam. Graphene foam consists of graphene assembled in a porous macroscale foam-like structure. The porosity of the foam makes the effective thermal conductivity of graphene foam very low, with a thermal conductivity of 0.26 to 1.7 W m −1 K −1 at a solid concentration of around 0.45 vol% [ 177 ].In summer, black asphalt pavement can absorb a considerable amount of solar radiation, which causes its temperature to rise. Heated asphalt pavement can aggravate the urban heat island (UHI) effect and transfer heat downward, which may cause the problem of permafrost thawing beneath pavements.
