振动法水泥稳定破碎砾石基层及工程应用研究

采用振动试验方法（VTM）设计水泥稳定破碎砾石（CSG）并进行工程应用。结果表明:破碎砾石的压碎值为10.7%，满足路面基层的使用要求；当水泥剂量为3.5%时，振动法CSG的无侧限抗压强度代表值达到6.9 MPa；比起传统的设计方法，VTM可降低水泥剂量并提高力学强度；工程实践表明，振动法CSG基层的使用效果良好。

Research on Cement-stabilized Broken Gravel Base by Vibration Method and the Engineering Application

Herein vibration test method (VTM) was used for the design of cement stabilized gravel (CSG), and then its engineering application was studied. The result shows that, the crushing value of the gravel is 10.7%, meeting the requirement of road basement; when the cement content is 3.5%, the typical value of unconfined compressive strength of the VTM-CSG reaches 6.9 MPa; compared to the traditional design method, VTM allows to reduce cement content and may enhance mechanical strength. The engineering practice has demonstrated that the VTM-CSG base may give a good use effect.
