Properties evaluation of asphalt-based composites with graphite and mine powders

Oriented heat release in asphalt pavement induced by high-thermal-conductivity rods

“…The study on the bidirectional heat-induced structure showed that increasing the thermal conductivities of asphalt mixtures in the middle and bottom layers could accelerate the heat transfer from pavement to subgrade, decrease the accumulated heat within pavement and then reduce pavement temperature [6]. However, since excessive powders with high thermal conductivity such as graphite usually bring many negative effects [22], actually the regulating range of thermal conductivity value is very limited [23e26]. This hinders the further increase of heat transfer rate, i.e., pavement cooling speed.…”

Cooling asphalt pavement by a highly oriented heat conduction structure

“…As the dosage of powder can significantly affect the volume index and performances of asphalt mixture [39], the maximum dosages of floating beads and graphite were both less than 15% of asphalt volume.…”

Nanosensors for Embedded Monitoring of Construction Materials: The “2D Conformable” Route

“…4 Full conformability is planned for the next stage of development. Force sensors based on piezoresistive nanocomposites have revealed themselves as a promising alternative [ 11 ] as they directly use construction materials, are expected to be low cost even for large areas and have good road compatibility, enhancing lifetime. However, they raise some concerns: large volumes of materials are required to replace the full pavement thickness so that signifi cant quantities of (expensive) nanoparticles are required.…”
