Aging Performance and Structural Study on Bio-Asphalt

Abstract:

This paper explains and demonstrates the aging performance and structure of bio-asphalt with analytical results from hot stage microscopy, infrared spectroscopic and nuclear magnetic resonance spectra. The experimental results showed that the aging of bio-asphalt is mainly caused by a large amount of coke substance generated during the process, and the addition of BHT can improve the aging resistance of bio-asphalt to some extent. Catalytic hydrogenation facilitate the removal of aldehyde, ketone and carbon-carbon double bond so as to strengthen the aging resistance of bio-asphalt, nuclear magnetic analysis further confirms the results from IR .
