浅析热拌沥青混合料级配微分布与离析控制

Superficial Analysis of Differential Distribution of HMA Gradation,and Segregation Controllling

针对高速公路路面工程重载交通特点,结合我省热拌沥青混凝土路面施工工艺和国外级配微分布研究成果,讨论现场热拌沥青混合料离析,尤其沥青混合料拌和站热料仓级配离析控制的重要性,提出热拌沥青混合料级配控制、设计、粗细集料作用发挥的建议。

Aiming at the features of havey load traffic on freeway, in the light of construction technology for HMA pavement in our province and the fruits of researching the differential distribution of gradation abroad, the paper discusses the segregation of HMA in situ, especially the importance of segregation controlling of HMA mixed at mixing plant, furthermore makes suggestions for playing the role of HMA gradation controlling and designing as well as the coarse and fine aggregates.
