摘　　要：采用Supperpave级配设计方法,结合马歇尔试验验证,在室内试验研究的基础上,提出了通赤高速公路沥青稳定碎石柔性基层的配合比,并在通赤高速公路得到成功实施。后期观测结果表明,柔性基层具有良好的抗裂性、耐疲劳特性,能有效延缓沥青路面的早期开裂,提高了沥青混凝土路面的服务质量。In the study, the flexible asphalt treated base＇s gradation design is provided about the highway from Tongliao to Chifeng based on some methods, including Superpave gradation design, Marshall testing validation and indoor testing re- search,And the fruit has been applied in the highway successfully. The later observation＇s results indicated that the flexible base has excellent anti-cracking and anti-fatigue performance, which can delay the road surface＇s premature cracking and finally improve the asphalt pavement＇s service performance.
