摘要
依据新颁发的《公路路面基层施工技术细则》,选取32.5硅酸盐水泥、石灰岩集料,合理确定各档集料比例及混合料最佳含水率和最大干密度,进行无侧限抗压强度和允许延迟时间试验,测试结果满足规范要求,同时绘制了水泥用量标准曲线,用于施工过程中水泥用量的检测与控制。
According to the newly issued specification“Technical guidelines for construction of highway roadbases”,32.5 Portland cement and limestone aggregate are selected to determine the aggregate proportion of each grade,the optimum moisture content and maximum dry density of the mixture.The unconfined compressive strength and allowable delay time test are carried out,and the test results meet the requirements of the specification.At the same time,the standard curve of cement consumption is drawn for detection and control in the construction process.
