Abstract
In order to study the fume suppressive effect of SBS and nano calcium carbonate， this paper studied the fume suppression laws of SBS and nano calcium carbonate， and carried out ratio test of SBS and nano calcium carbonate, and got the conclusions that: With the increasing adding level of SBS and nano calcium carbonate, the asphalt fume productive rate will reduce gradually and will reach a condition of stability. The adding level of 4% of SBS is a turning point. When less than 4%, the asphalt fume production rate decreased rapidly; and more than 4%, the asphalt fume production rate decreased slowly; when adding nano calcium carbonate at the level of 5%, the asphalt fume won’t decrease. The best ratio of SBS and nano calcium carbonate is 6% of SBS and 6% of nano calcium carbonate, with which asphalt fume reductive rate was up to 30%.
