摘要
沥青混合料的高温稳定性是重要的研究课题,结合几种AC-20I型级配沥青混合料的高温稳定性实测数据,讨论了Superpave级配图中混合料级配曲线与高温稳定性的关系.结合Superpave的限制区和控制点理论提出AC-20改进型级配,并给出其合理的马歇尔试验技术指标的推荐值.
Study of the stability of AC-20I asphalt mixture is very important. Through analyzing the test data about the stability of several AC-20I asphalt mixture, the relation between grading curves in grading drawing of Superpave and stability is discussed. By using superpave theory about restricted zone and control point, the improved AC-20 grading and its reasonable proposal limit of technical parameter of Marshall test are raised.
