摘　　要：在对级配碎石原材料质量提出严格技术要求的前提下,对用于高速公路倒装结构的级配碎石防裂基层的级配和回弹模量进行了分析和研究,设计了一种强度高、渗(排)水能力大、施工性能好的骨架嵌挤密实型的级配碎石级配,并通过试验路对该级配的性能进行了验证。under the strict specification premise for raw material of graded broken stone, this article give a experiment research on grade and module of graded broken stone used for base of guard against the crack in expressway inversive Structure, then design a interlock and filled grade of graded broken stone that have high strength and infiltrated （draining） water rapid, construction easy. At last the research give a confirmation by a experiment road.
