Cement dosage estimation method and system for skeleton compact type cement stabilized macadam
The invention discloses a cement dosage estimation method for skeleton compact type cement stabilized macadam, and the technical scheme is as follows: the cement dosage estimation method comprises thefollowing steps: designing a skeleton compact type grading curve, obtaining mineral aggregate gradation with smaller mineral aggregate void ratio, and obtaining density parameters; establishing a cement content estimation formula; obtaining an estimated value of the cement content according to the density parameter and a cement content estimation formula; and determining the cement dosage for thetest by taking the estimated value as a reference, and obtaining the optimal cement dosage through the confirmation of the performance test. According to the method, the reasonable minimum cement dosage of the skeleton dense gradation can be determined through a small number of tests.
本发明公开了一种骨架密实型水泥稳定碎石的水泥剂量预估方法，其技术方案为：包括：设计出骨架密实型级配曲线，获得较小矿料间隙率的矿料级配，并获取密度参数；建立水泥含量预估公式；根据密度参数及水泥含量预估公式获得水泥含量的预估值；以预估值为基准确定试验用的水泥剂量，并通过性能试验的确认获取最佳的水泥剂量。本发明能够通过少量试验来确定骨架密实级配的合理的最小水泥剂量。
