针对两种星型SBS改性剂和一种线型SBS改性剂对日本AH - 70 #沥青和埃索AH - 70 #沥青的改性效果进行了研究。试验结果表明对于这两种基质沥青星型改性剂的最佳掺量为 4 .5 % ,线型改性剂的最佳掺量为 5 .0 %。并根据工地的实际情况进行了配合比设计。
The effects of two star - type SBS modifiers and one type of linear SBS modifiers on the modification of Japanese AH - 70 # asphalt and Esso AH - 70 # asphalt were studied. The test results show that the best dosage of the two types of matrix asphalt star modifier is 4.5%, and the best dosage of the linear modifier is 5.0%. And according to the actual situation of the site with the ratio of design.
