Investigation on Properties and Mechanism of HPCM Stabilizing Roadbed of Expressway

  • Received Date: 28 Apr 2008
  • Publish Date: 25 Dec 2008
  • To enhance the stability of soil filled in the roadbed of expressway,a high performance consolidating material(HPCM) was used to improve the stability of primary soil,and its performances such as CBR(California bearing ratio) value,compactness and expansion were investigated through a physical test,SEM(scanning electron microscopy) and XRD(X-ray diffraction) analyses.The research result shows that the CBR value of soil treated by HPCM is increased.Different from conventional approaches to stabilize roadbed,the mechanism of HPCM is to form a tight structure by increasing the combination of soil grains through the interaction of physical and chemical effects to enhance the stability of treated soil.
