Energy Harvesting from Thermoelectric Effects of Pavement Materials

Abstract

Nowadays, there are initiatives to replace fossil fuel energy with energy from renewable sources, such as solar, water, wind, and others. The thermoelectric effect is another fascinating source of energy. This research aims to examine the viability of using thermoelectric technology to asphalt pavement materials in the future as a renewable energy source, as well as the thermal conductivity qualities of asphalt with various composite materials. The steel fiber and graphite powder were added to the mixture of pavement materials designed with reference to road work standards of the Department of Highways of Thailand. Simulate the pavement environment to replicate the daytime and nighttime surroundings. The temperature, voltage, and current values were then gathered for analysis. The findings indicate that asphalt pavement material is suitable for energy generation via thermoelectric technology. Graphite-infused pavements have significantly enhanced heat retention properties. Adding steel fiber also increases its capacity to store heat, but to a lesser extent than graphite.
