Background Materials play an important role in the transportation infrastructure. Globally, about 90% of roads are made of asphalt mixtures. In the United States, 500 million tons of asphalt mixtures are produced annually at a cost of around $40 billion. Improving pavement materials properties, such as thermal conductivity and expansion-contraction,...

­Background In road infrastructure, one of the important properties of addressing the environmental and urban heat island aspects of pavements is the determination of the thermal conductivity. Asphalt concrete represents the third most widely used resource in the world, with asphalt-paved roads being its principal usage. One of the most important...
