水泥稳定砂砾基层在高速公路施工中的应用

Application of Cement-Stabilized Sand Gravel Base in Expressway Construction

水泥稳定砂砾基层为半刚性基层,其具有整体性好、强度大、刚度大以及稳定性高等特点,适合作为底基层和基层,因此在高速公路施工中广泛应用。结合具体的高速公路施工实例,从施工准备、工艺流程等方面探讨水泥稳定砂砾基层的应用,希望为类似工程提供参考与借鉴。

Cement-stabilized sand gravel base is semi-rigid base, which has good integrity, strength, stiffness and high stability. It can be used as subbase and base, so it is widely used in expressway construction. Combined with the specific example of one highway construction, the application of cement-stabilized sand gravel base is explored from aspects of construction preparation and process, in hope of providing reference for similar projects.
