滨海地区细砂分布广泛，若能采用滨海细砂作为路基填料使用，则不仅能解决该区域公路建设所需优质路基填料匮乏的问题，而且能产生显著的经济社会效益。在对海南省滨海地区砂源进行广泛调研的基础上，选取几种典型砂样，进行了颗粒分析、击实特性、CBR、回弹模量、抗剪强度等物理力学试验，并对其路用性能进行了评价。试验结果表明：滨海细砂的路用性能良好，其满足现行技术规范的要求，可以作为公路路基填料。

Fine sand is widely distributed in coastal area.If it can be used as highway subgrade filling by find sand of the coastal area,it can not only solve the problem of regional highway construction required high quality subgrade filling shortage,but also can generate significant economic and social ben-efits.In this paper,based on extensive investigation on the source of fine sand in coastal area of Hainan Province,a series of laboratory tests were performed for several typical fine sand,including the experi-ments of sieve analysis,compaction characteristic,CBR,modulus,shear strength,and evaluated its highway performance.The researching result indicates that fine sand of the coastal area is in good high-way performance.It can meet the current specification requirements,so it can be used as highway sub-grade filling.
