SBS 改性沥青技术与效果评价

Technology and Effect Appraising about SBS Modified Asphalt

采用高速剪切设备制备了ＳＢＳ改性沥青，在ＳＢＳ掺量为６％时形成网状结构。ＳＢＳ改性沥青的高温性能和低温性能均有显著改善，且改性效果与原沥青的组分组成有关。

SBS modified asphalt is made by using the high speed shear equipment. When the quantity of SBS in the asphalt is up to 6%, the three dimensional network is formed. The high temperature property and low temperature property of SBS modified asphalt are improved, meanwhile, the effect is related with the component of original asphalt.
