摘　　要：通过试验研究了级配碎石强度的诸多影响因素,包括矿料岩性、颗粒形状、级配类型等,分析了各影响因素的影响规律及机理,为级配碎石混合料的设计提供理论依据。此外,通过实体工程的铺筑,提出了分别适合高速公路基层、底基层和路基改善层的级配碎石类型。Through the tests,many factors affecting the strength of graded crushed stone were studied,including rock lithology,particle shape,graded type,etc.,and the influencing rules and mechanisms of each factor were analyzed,providing theoretical basis for the design of graded crushed stone mixture.In addition,the graded crushed stone types suitable for expressway base,subbase and subgrade improvement layer are proposed through the paving of solid engineering.
