Abstract：The asphalt mortar composited with different proportion of magnetite/activated carbon was prepared,low temperature performance,high temperature performance,shear strength and temperature susceptibility were tested. And magnetite powder/activated carbon powder for the effects of improving the performance of asphalt mortar was analyzed. The results show that high temperature performance of asphalt mortar was significantly improved with decrease of the magnetite powder/activated carbon composite ratio, however,its low temperature performance was reduced to a certain extent,thus it was suggested composite ratio larger than 60:40. Cone penetration of asphalt mortar sensitive coefficient and viscosity temperature index showed a consistent change rules. The incorporation of activated carbon powder significantly reduced the temperature sensitivity of asphalt mortar.
