摘要
在分析砂土工程特性的基础上,拟采用水泥稳定法处治某二级公路细砂路基;根据击实试验及CBR值、回弹模量测试结果,最终确定出水泥改良砂的最佳水泥用量为3%,最佳用水量为11.5%。工后对试验段路床顶面弯沉及压实度进行检测,结果表明均满足规范及设计要求。
According to the analyze on the engineering properties of sand soil,the paper decided to use cement stabilized treatment to deal with the sand soil subgrade on an secondary road; It shows that modified cement sand has 3% optimum amount of cement and 11. 5% optimum amount of water,based on compaction test CBR values,resilient modulus test results. The testing results of road bed deflection and compaction degree results can meet the specifications and design requirements after the construction.
