Comparative analysis of reactive rejuvenation strategies for aged SBS modified bitumen: insights from volatile organic compounds emission characteristics and performance evaluation SCIE

Abstract :

In order to investigate the effects of reactive rejuvenation strategies on volatile organic compounds (VOCs) emissions and the performance of aged SBS modified bitumen (SMB), gas chromatography-mass spectrometry test, physical property tests, and rheological property tests were utilized to evaluate the effectiveness of bio-oil, the epoxy-based rejuvenator, the isocyanate-based rejuvenator and the composite reactive rejuvenator. A multicriteria evaluation model integrating rejuvenation effectiveness, environmental impact, and health risk was then applied to identify the optimal reactive rejuvenator. Results show that all rejuvenators increase the VOCs emission concentration and the proportion of oxygenated volatile organic compounds (OVOCs), along with varying degrees of elevation in ozone formation potential, secondary organic aerosol formation potential, carcinogenic risk, and hazard index. Bio-oil has limited rejuvenation effectiveness and holds the lowest overall ranking. The epoxy-based rejuvenator provides rejuvenated SMB with numerous flexible chain segments that exhibit considerable rotational freedom, which contributes to improved low temperature cracking resistance. However, it poses the highest environmental and health risks. The isocyanate-based rejuvenator imparts rigid molecular structures that enhance the deformation resistance of rejuvenated SMB, albeit at the expense of reduced flexibility. The composite reactive rejuvenator exhibits superior rejuvenation effectiveness with the lowest environmental and health impacts.
