摘要
通过对SBS/白炭黑复配改性沥青基本性能的测试,研究了不同用量的白炭黑对SBS改性沥青性能的影响。结果表明：3%白炭黑的加入量使SBS改性沥青的5℃延度略有下降,当量脆点(T_(1．2))值下降；3%白炭黑加入提高了SBS改性沥青的高温性能及感温性。
the properties of SBS modified asphalt with silica hydrated was tested, and the influence of different content of silica hydrated on properties of SBS modified asphalt was also researched. The results showed that when the silica hydrated was added into 3 percent of modified asphalt, the 5℃ ductility and Ti.2 were decreased, and the high-temperature behavior and sensitivity for temperature of SBS modified asphalt were increased.
