【正文】 t and improve service performance, can significantly extend life, reduce noise, increase fort and safety, SBS asphalt, as a kind of modified asphalt cementing material, in the early 1990 s already appeared, because the SBS is a kind of China has not widespread. In this paper, we mainly discuss SBS modified asphalt construction technical . key words: SBS asphalt mixing ratio of design technical requirements construction quality control 3 目錄 第一章 發(fā)展概況 ............................................................................................................. 1 SBS改性瀝青簡(jiǎn)介 ............................................................................................... 1 SBS改性瀝青機(jī)理 ............................................................................................... 1 SBS改性瀝青的特性 ............................................................................................ 2 SBS改性瀝青的生產(chǎn) ............................................................................................ 2 改性瀝青的技術(shù)標(biāo)準(zhǔn) ............................................................................................ 2 第二章、 配合比設(shè)計(jì) ........................................................................................................ 7 材料選擇與準(zhǔn)備 .................................................................................................. 7 粗集料 ...................................................................................................... 7 細(xì)集料 ...................................................................................................... 7 填充料 ...................................................................................................... 7 SBS改性瀝青技術(shù)要求 ............................................................................ 8 SBS改性瀝青試驗(yàn)中應(yīng)注意的問題 ........................................................... 9 瀝青混合料配合比設(shè)計(jì) ........................................................................................ 9 級(jí)配 .......................................................................................................... 9 粉 膠 比 .................................................................................................... 10 馬歇爾試驗(yàn) 混合料技術(shù)指標(biāo) ..................................................................... 10 試驗(yàn) 注意事項(xiàng) ........................................................................................... 10 確定最佳瀝青用量 (或油石比 )....................................................................11 第三章 、 SBS 瀝青混合料的施工 ..................................................................................... 15 運(yùn)輸?shù)募夹g(shù)要求 ................................................................................................ 15 瀝青拌合場(chǎng)儲(chǔ)存的技術(shù)要求 .............................................................................. 15 泵送的技術(shù)要求 ................................................................................................. 15 拌合、運(yùn)輸?shù)募夹g(shù)要求 ...................................................................................... 16 攤鋪的技術(shù)要求 ................................................................................................. 16 碾壓 與成型 的技術(shù)要求 ...................................................................................... 17 SBS瀝青混合料的質(zhì)量控制 ............................................................................... 19 .................................................................................. 19 ..................................................................................... 20 第四章、總結(jié) ................................................................................................................. 22 參考文獻(xiàn) ........................................................................................................................ 23 致謝 ............................................................................................................................... 23 改性瀝青配比和施 工 1 第一章 發(fā)展概況 SBS 改性瀝青簡(jiǎn)介 SBS 改性瀝青是在原有基質(zhì)瀝青（ AH70）的基礎(chǔ)上，摻加 %、 %、％的 SBS 改性劑，改性后的瀝青，與原瀝青相比，其高溫粘度增大，軟化點(diǎn)
