Superpave沥青混合料配合比设计方法的实践应用

Application of Design Method for Mixture Ratio of Superpave

运用美国 Superpave热拌沥青混合料配合比设计理念 ,采用旋转压实仪 (SGC)方法 ,通过对改性沥青结合料、SMA- 16沥青混合料试验检测及各项指标分析 ,综合评定长余高速公路 SMA- 16结构改性沥青混合料级配的可行性 ,并进一步指导路面施工。

Adopting the SGC method in HMA formulation design, aggregates, binder and SMA-16 mix are tested and the various indexe analyzed, then the gradation rationality of SMA-16 mix in Chang-Yu Expressway is synthetically appraised in order to instruct the pavements.
