SBS掺量和类型对SBS改性油浆改质沥青性质影响

Effect of SBS Content and Type on Properties of SBS Modified Asphalt with FCC Slurry

催化裂化(FCC)油浆的综合利用已成为现阶段研究的焦点之一。由于催化裂化油浆富含芳烃,可作为生产道路沥青的有效调和组分。本文选取掺量分别为3.5%、4.0%、4.5%和5.0%的线型SBS(YH-791)和星型SBS(LG-411)分别改性自制油浆改质沥青(AFS),考察了SBS掺量和类型对SBS改性油浆改质沥青(SMAFS)性质的影响,确定了SBS改性油浆改质沥青的线型和星型SBS最佳掺量均为4.5%。

Comprehensive utilization of Fluid catalytic cracking （FCC） slurry has become one of the hotspots ot thestudy at this stage. FCC slurry with rich in aromatic is the effective blending component for the production of road asphalt.With contents of 3.5%, 4. 0%, 4. 5% and 5.0% linear SBS （ YH-791 ） and radial SBS（ LG-411 ） modified asphaltwkh FCC slurry（AFS） , respectively, content and type of SBS influenced on the properties of SBS modified asphalt withFCC slurry（SMAFS） was investigated. Moreover, the optimum content of linear SBS or radial SBS for SMAFS was 4. 5%.
