摘要
采用颗粒状SBR橡胶对塔河稠油基质沥青进行提质改性研究,并与块状橡胶SBR1502改质效果进行比较研究。结果表明:颗粒状橡胶SBR对塔河稠油沥青改性与块状橡胶SBR改性效果相当,使用更方便安全。颗粒状橡胶SBR特别对基质沥青延度指标改善效果显著,浅度改性生产90号重交沥青,其90号沥青热储存质量稳定,沥青混合料主要性能指标均满足JTG F40—2004《公路沥青路面施工技术规范》规范要求。
Granular rubber SBR is used to modify matrix asphalt from Tahe heavy oil.The modification effect is compared with that of block rubber SBR 1502.The results show that the modification effect of granular rubber SBR is the same as that of block rubber SBR in Tahe heavy oil asphalt Granular rubber SBR is more convenient and safer in use.Granular rubber SBR has remarkable effect of improving ductility index on matrix asphalt.If it is used for producing No.90 heavy traffic paving asphalt,the asphalt has stable thermal storage quality,and its performance indicators can meet the requirements of JTG F40-2004 specification.
