土壤固化剂在高速公路路基处理中的应用

在开展季冻区柔性基层沥青路面结构组合研究过程中，级配碎石基层强度较低，为了保证路面结构的安全和降低沥青层的厚度，需提高级配碎石基层的土基强度。此外，级配碎石材料具有明显的非线性，其下土基强度的高低将直接对级配碎石强度的发挥有着重要的影响。因此，对于级配碎石基层沥青路面，需对土基采取加强措施，以利于结构层整体功能的发挥。通过对固化剂工作原理和路用性能的分析，阐述了土壤固化剂的适用范围和施工方法，既可充分利用当地资源，又为以后高等级公路土基处理提供一定的参考。

Application of Soil Stabilizer in the Highway Roadbed Treatment

during the study of combination of flexible base asphalt pavement structure in the seasonal frozen region, the strength of grading crushed stone base is low, to guarantee the safety and reduce the thickness of asphalt layer, we need to improve the strength level of subgrade . In addition, the material of grading crushed stone has obvious nonlinear characteristics, The strength of subgrade has an important influence on the strength crushed stone. So for the grading crushed stone asphalt pavement, we need to take measures to improve strength. By working principle and road performance analysis of soil stabilizer, outlined the scope and construction of soil stabilizer. Both the full use of local resources and provide a reference for the future subgrade treatment. of grading the overall method of of highway
