| 摘 要： | 在考虑干缩特性的同时，经分析得出影响水泥稳定碎石强度的主要因素，同时以这些因素为基础，选用正交试验法，通过三点控制确定的幂函数级配求解出9种级配，得出各因素与各指标的关系，最后根据各级配的试验指标可调整计算出水泥稳定碎石的最佳级配．这便是无机稳定碎石类材料新的设计方法。

| Abstract: | The main factors influencing strength of cement stabilized crushed stone are deduced when considering dry shrinkage performance. Orthogonal experimental method is adopted based on these factors, obtaining 9 gradation through 3 points controlled power function and relationship among every factor and every index. Finally the optimum gradation of cement stabilized crushed stone is calculated according to the experimental index of each gradation. This is design method of inorganic binder stabilized crushed stone material. |
