| 摘 要： | 级配碎石层材料的强度较低。主要来源于碎石颗粒本身的强度以及碎石颗粒之间的嵌挤力。为了得到较高强度和稳定性的材料，采用反映材料强度的指标CBR值。对级配碎石的级配以及试件的成型方式这两个影响因素进行了分析。

| Abstract: | The strength of graded broken stone is low and it depends on the strength of granule in itself and the interaction between granules. For gaining high strength and stability of unbound aggregate, CBR is used as an index that reflects the strength of material, the impact of gradation and shaping modes for the graded broken stone are analyzed. |

| Keywords: | graded broken stone CBR value gradation shaping mode |
