摘　　要：为了解公路施工过程中产生的大粒径碎石作为路基填料的压实性能,以某高速公路隧道弃渣为例,通过对大粒径碎石填料室内振动压实原理的分析,采取了不同级配的大粒径碎石共7组混合料,采用筛分法进行了颗粒分析试验,并进行了填料的室内振动压实试验,试验结果可为今后公路路基中大粒径碎石填料的应用提供了有益的参考。In order to know the compaction property of large grain size macadam during the highway construction as the subgrade filling,taking waste slag of an expressway tunnel as the example,through the analysis on laboratory vibration compaction theory of large grain size macadam filling,large grain size macadam with different gradation are adopted to compose 7 groups of mixtures,the test on grain size analysis is performed by adopting sieving method,and the laboratory vibration compaction test on the filling is performed. The test results can provide useful reference for the application of large grain size macadam in highway subgrade in the future.
