Abstract
Bitumen additives that can reduce emissions in bitumen and asphalt are desirable for managing or mitigating harmful or odorous emissions during infrastructure projects. Assessing and comparing the relative performance of different additive classes is crucial for determining their significance in emission reduction. In this study, a range of additive classes were investigated, including commercial additives, natural products, synthetic chemicals, biomolecules, and solid adsorbents. Headspace gas chromatography-mass spectrometry (HS-GC-MS) was used to measure the release of volatile organic compounds (VOCs) from bitumen after the incorporation of these additives. Among the additives investigated, solid adsorbents such as biochar materials were the most effective in mitigating the emissions of the monitored VOCs by up to 50%. These results suggest that biochar, may be prioritized for managing VOC emissions in asphalt-related projects.
