摘　　要：为全面提升公路工程砂性土路基应用质量,要践行规范化技术手段,确保填筑施工作业等环节有序开展,在系统评估砂性土路基结构特殊性后,针对其特点展开相应作业,进一步提高砂性土路基结构强度。基于此,文章首先从工程性质、分类、最大干容重三个方面分析公路工程砂性土路基,然后结合某市高速公路A支线工程案例,对公路工程砂性土路基填筑施工技术的具体应用展开分析,以期为类似工程提供参考。In order to comprehensively improve the application quality of sandy soil subgrade in highway engineering, it is necessary to practice standardized technical means to ensure the orderly development of filling construction operation and other links. After systematically evaluating the particularity of sandy soil subgrade structure, corresponding operations are carried out according to its characteristics to further improve the structural strength of sandy soil subgrade. Based on this, this paper first analyzes the sandy soil subgrade of highway engineering from three aspects of engineering nature, classification and maximum dry volumetric weight,and then analyzes the specific application of sandy soil subgrade filling construction technology of highway engineering in combination with the case of A branch line project of a city expressway, in order to provide reference for similar projects.
