摘要：
To make nano calcium carbonate as the modifier, firstly the best proportion of nano calcium carbonate is determined as 6% by comparing the influences of different proportions of nano calcium carbonate to the indexes of asphalt. Then the influence of mixing with nano calcium carbonate to the performance of asphalt concrete AC-13 has been studied. Tests show that, the mixing of 6% nano calcium carbonate has improved the dynamic stability of asphalt concrete AC-13 from 991 times/mm to 1269 times/mm; the residual stability from 0.87 to 0.94. This indicates that after mixing with nano calcium carbonate, both the high temperature performance and water stability of asphalt concrete have been improved.
