Research on Dynamic Modulus of SBS Modified HMA

摘要

First of all, the test samples of SBS modified HMA are prepared. And then, dynamic modulus experiment is executed. Based on the experiment, the variation law of dynamic modulus of SBS modified HMA in the light of influence factors such as test temperature, loading frequency and tfi-axial confining pressure is formulated. Furthermore, the respective reasons are also explained. Last but not least, the variation law is compared with ordinary HMA and the similarities and dissimilarities of the two sorts of HMA is discussed briefly.
