摘要
级配碎石作为沥青路面的上基层,其配合比设计是形成其强度的主要原因。从级配碎石基层的研究现状出发,利用料样级配和设计配合比对级配碎石进行合成配合比设计,深入分析了级配碎石基层的施工工艺。
Graded as gravel on the asphalt pavement of the grassroots, with its form than its design strength is the main reason. From the grassroots macadam research, using materials like size distribution and mix design of the graded gravel composite mix design, the graded gravel grassroots construction technology are analyzed.
