以SBS为改性剂,对石油沥青和中温煤沥青进行混合改性.研究了软化煤沥青、SBS改性对沥青流变性能的影响.实验结果表明,质量分数为15%软化煤沥青与石油沥青混合,经质量分数为5%SBS改性后得到的混合改性沥青流变性能较好,其延度为108 cm,软化点达到85 ℃.

he petroleum asphalt and coal tar pitch were modified by SBS as a modifier. The influences of the softening coal tar pitch and SBS modification on the rheological properties of asphalt were studied. The results show that the hybrid modification asphalt mixed with 15% softening coal tar pitch and petroleum asphalt has better theological properties after modified by 5% SBS, of which the ductility and softening point are 108 cm and 85 ℃.
