HARNESSING RENEWABLE ENERGY FROM LOW-CARBON GEOTHERMAL PAVEMENTS

Grant number: LP170100072 | Funding period: 2018 - 2021

Completed

Abstract

This project aims to investigate the extraction of renewable energy from new pavements constructed with low-carbon recycled demolition wastes. The proposed research will generate new knowledge on the thermo-geomechanical responses of pavements when harvesting heat energy under dynamic loads, using experimental and numerical approaches, including field trials. The outcomes and benefits will include strategic long-term collaboration with industry to develop ‘Geothermal Pavements’, with potential for commercial applications. The translation of this research will contribute to meeting future energy needs, while significantly reducing carbon emissions and diverting demolition wastes from landfill..
