摘　　要：针对二灰砂砾在实际应用中集料最大粒径的控制方法、适宜的最大粒径、减少离析的施工工艺控制、现场压实度测定等问题进行了研究,研究表明,沥青路面的承载能力完全可以由二灰砂砾结构层满足,二灰砂砾完全可以适用于高等级公路基层结构中。In light of the practical application of fly ash-lime grit, the following paper studies the method to control the maximal granule diameter of aggregate, the appropriate maximal granule diameter, construction technological control to reduce separation, and the measuring of in situ pressuring degree, and shows that fly ash-lime grit structural layer can satisfy the bearing capacity of bituminous pavement and fly ash-lime grit is fit for foundation structure of high-grade highway.
