Abstract:: To investigate the influencing factors and mechanisms of fume release from crumb rubber modified as-phalt,based on the preparation of different crumb rubber modified asphalts, a self-developed fume generation and detection device was utilized, combined with three detection methods including gravimetric method, portable gas detector, and gas chromatography-mass spectrometry(GC-MS) to determine the concentrations of asphalt fumes and harmful components. The grey relational analysis was performed to evaluate the relationship between various factors and fume concentrations. Further characterization using four-component analysis, infrared spectroscopy, and fluo-rescencemicroscopy was conducted to explore how different factors affect the underlying mechanisms of fume re-lease.The results showed that the base asphalt grade and additive type were the main factors affecting asphalt fume release. The four-component test showed that fumes from crumb rubber modified asphalt mainly came from the vol-atilizationof light components. The infrared spectroscopy test indicated that the contents of aromatic hydrocarbons and alkanes were the main factors affecting fume and VOCs concentrations,while the total sulfur content in asphalt was the key factor controlling H₂S release. The fluorescence microscopy test further confirmed that a stable internal structure could suppress fume release from crumb rubber modified asphalt to a certain extent.
