摘要：

At different air voids designed, various kinds of asphalt mixture were chosen for fatigue performance comparison with self-healing effect considered. Nf50 criterion was selected to judge the fatigue lives of matrix asphalt mixtures, while NfNM criterion was selected to judge the fatigue lives of modified asphalt mixtures. The results show that when the self-healing effect is not considered, AC-13 terminal blend (TB) rubber powder+SBS modified asphalt mixture has the best fatigue life, followed by ARAC-13 rubber asphalt mixture, AC-13 SBS modified asphalt mixture and AC-13 TB rubber powder+rock asphalt modified asphalt mixture, et al. When the self-healing effect is considered, ARAC-13 rubber asphalt mixture has the best fatigue life, followed by AC-13 TB rubber powder+SBS modified asphalt mixture, AC-13 SBS modified asphalt mixture and AC-13 TB rubber powder+rock asphalt modified asphalt mixture, et al. TB rubber powder modified asphalt mixture and kinds of composite modified asphalt mixture based on TB rubber powder are of important scientific and practical application value. © 2015, Tongji University.
