| 摘 要： | 近年来改性沥青在道路工程的大量使用,满足了工作性要求,却在施工过程中产生了大量烟尘等废弃物。而降低拌和温度是较好的办法,于是出现了温拌技术。该文以新疆克拉玛依90#A级沥青为研究对象结合温拌技术,研究掺加不同剂量的Sasobit对沥青的四种组分的影响及由此引起的变化,以确定Sasobit的合理掺量。

| Abstract: | In recent years,modified asphalt was quite used in road,which met the work requirements,but produced a lot of dust and other wastes in the construction process.Warm mixing technology that was a better way to reduce mixing temperature came.was based the Karamay 90 # A-level asphalt was the main object based on warm mixing asphalt technology in the study.The four components of the asphalt would be changed at different Sasobit dosages.The reasonable Sasobit dosage was decided between 3%and 4% finally. |
