【摘要】：為更合理控制SBS改性瀝青的質(zhì)量性能,選取不同的剪切時(shí)間、剪切溫度和發(fā)育時(shí)間,對(duì)3種不同的SBS改性瀝青進(jìn)行改性加工;應(yīng)用瀝青試驗(yàn)方法與熒光顯微觀測(cè)技術(shù),對(duì)其感溫性、高溫性能、低溫性能,以及改性瀝青的微觀分散狀態(tài)進(jìn)行了分析研究。研究結(jié)果表明:對(duì)與瀝青相容性較好且相對(duì)分子質(zhì)量較大的SBS,加工工藝參數(shù)推薦剪切時(shí)間90min,剪切溫度180℃,發(fā)育時(shí)間2h;對(duì)與瀝青相容性較差且相對(duì)分子質(zhì)量較小的SBS,加工工藝參數(shù)推薦剪切時(shí)間60min,剪切溫度170℃,發(fā)育時(shí)間不宜大于4h。結(jié)合研究結(jié)果對(duì)現(xiàn)場(chǎng)膠體磨的加工工藝參數(shù)進(jìn)行了優(yōu)化,能保證現(xiàn)場(chǎng)生產(chǎn)的SBS改性瀝青的質(zhì)量要求。
[Abstract]:In order to control the quality of SBS modified asphalt more reasonably, three kinds of SBS modified asphalt were modified and processed with different shear time, shear temperature and development time. The temperature sensitivity, high temperature performance, low temperature performance and micro dispersion state of modified asphalt were studied. The results show that for SBS with good compatibility with asphalt and relatively high molecular weight, the processing process parameters recommend shear time of 90 min and shear temperature of 180 鈩，
