Abstract:
Considering the technical requirements of heavy load pavement in hot and moist areas, the performances of semiflexible pavement with asphaltrubber(ARSFAC), such as the high temperature stability, low temperature anticracking and moisture susceptibility, are tested. The characteristics of ARSFAC are compared with those of the asphaltrubber concrete mix (RAC). The results show that: with the same binder, the dynamic stability of semiflexible pavement mixture with asphaltrubber (ARSFAC20) is much larger than that of rubber asphalt concrete (RAC16), and the retained stability and indirect split tensile strength after freezethaw of ARSFAC20 are higher than those of RAC16 by 18.2% and 14.1% respectively; the tensile strain at failure of the ARSFAC20 binders at -10℃ is higher than that of the RAC16, but the stiffness modulus of the ARSFAC20 is smaller than that of the RAC16. 10 tabs, 7 figs, 7 refs.
