粗粒土的路用性能试验研究

Research on the experiment of the road application property of coarse-grained soil

结合工程实例,对原材料的基本物理性质进行了分析,对不同粗颗粒质量分数及级配情况下的粗粒土进行了击实试验,并对其开展了无侧限抗压强度、CBR及回弹模量试验,试验结果表明,粗粒土的级配在泰勒理想级配范围内其压实性能最好。

Combined with a project, it analyses the basic physic property of raw materials. It makes a compaction experiment to the coarsegrained soil of different quality and gradation, and makes experiments such as unconfined compression strength test, CBR and resilience modulus test. Those experiments show that the compaction property of coarse-grained soil gradation is best in the range of ideal Tailor gradation.
