摘　　要：沥青混合料的级配曲线走向能够反映它的不同粒径颗粒间的相互嵌挤程度,通过对规范级配范围内的五条不同级配曲线走向进行试验研究,可以指导高速公路沥青混合料的级配设计,旨在评价不同级配曲线走向对混合料高温性能的影响,因为不同粒径颗粒间的相互嵌挤程度对高温性能影响很大。The trend of gradation curve of asphalt mixture can reflect the mutual interlocked degree among its particles with different grain size, Trough the experimental study on the trend of five different gradation curves of norm grading range, it can guide the gradation design of highway asphalt mixture, so as to evaluate the impact of different gradation curve trend on high temperature performance of mixture, because mutual interlocked degree among particles with different grain size has great impact on high temperature performance.
