Abstract

In this study, we examined the capacities of three additives, viz. wood powder, Al(OH)₃-loaded wood powder, and Mg(OH)₂-loaded wood powder, to reduce the emission of CO₂ from heated asphalt. We analyzed the effects of particle size and amount of wood powder additive, as well as the loading quantity of Al(OH)₃/Mg(OH)₂, on the concentration of CO₂ emission from heated asphalt. We performed surface morphology and elemental analyses of the modified and unmodified wood powders by scanning electron microscopy in combination with energy-dispersive X-ray spectroscopy. The results indicated that using wood powder additives reduced the emission of CO₂ from asphalt at high temperatures. Loading Al(OH)₃/Mg(OH)₂ was also found to improve the results. The optimal wood powder particle size, amount of wood powder additive, and Mg(OH)₂ loading amount were determined to be 80–100 mesh, 2%, and 4%, respectively. Specifically, the rate of reduction of CO₂ emission from asphalt reached 92.9–97.9% under these optimal conditions.
