摘要
为研究法赛(温拌沥青添加剂)对SBS改性沥青高低温性能的影响,采用软化点试验、动态剪切流变试验、延度试验以及弯曲梁流变试验,以测试其高低温性能的变化。试验结果表明:掺加法赛温拌剂后,SBS改性沥青的软化点和破坏温度值提升的最大幅度分别为16.0%和16.2%,使其高温性能得到较大的改善;但同时其延度和弯曲流变性能降低,低温抗裂性能变差。建议法赛温拌剂的合理掺量为3%。
In order to explore the effect of fasir(warm asphalt additives) on styrene butadiene styrene(SBS)modified asphalt binder 'high and low temperature performance,the softening point test,dynamic shear rheological test,ductility test and bending beam rheological test were conducted to evaluate the changes in its high and low temperature properties. Test results indicate that the maximum elevatory amplitude of softening point and fail temperature value of SBS modified asphalt binder with fasir are 16. 0% and 16. 2%respectively. The high temperature performance is greatly improved. But its ductility,bending rheological properties and low-temperature cracking resistance are reduced by fasir. Considering the SBS modified asphalt binder'high and low temperature performance with fasir,a mixing content with 3% fasir is recommended.
