Investigation of influence factors for sampling and quantification of organic emissions released from paving asphalt
During construction heating, asphalt releases significant emissions, posing risks to workers and the environment. There are various methods for sampling and analyzing asphalt emissions. However, the quantification results of asphalt emissions are affected by various factors, which is not well investigated. To fill this gap, asphalt emission samples collected under different conditions were dissolved in carbon disulfide and analyzed. Emissions, including polycyclic aromatic hydrocarbons (PAHs), benzenes, and benzothiazoles from crumb rubber modified asphalt (CRMA) and base asphalt, were quantified using gas chromatography-mass spectrometry (GC–MS). Based on the quantitative results under different influencing factors, a sampling procedure for asphalt emissions is recommended. The satisfactory spiked recovery rate of asphalt emission samples indicates the reliability of experimental results. Emission rates were comparable under different experimental conditions. This method can be used for further asphalt emissions reduction research, providing reliable data to support air quality improvement efforts.
期刊介绍:
Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution.
We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
