摘要
为了研究水泥冷再生材料的路用性能,特别是水泥剂量与无侧限抗压强度之间的变化规律,分析无侧限抗压强度与回弹模量、抗冲刷性能、干缩性能、疲劳性能之间的关系曲线,进行了一系列室内试验,并对试验数据进行了统计分析及数据拟合。拟合结果表明水泥强度与回弹模量、干缩性能、疲劳性能呈现良好线性关系,与抗冲刷系数之间存在一个指数函数关系。
In order to study road usage performance of cement cold regeneration blend material, especially variation regular between cement dosage and unconfined compressive strength, the author makes analysis on the curve for relation of unconfined compressive strength and modulus, anti-erosion properties, drying shrinkage, fatigue. After a series of laboratory experiments, and statistical analysis of experimental data and fitting of the data, it is shown of good linear relationship between cement strength and modulus, drying shrinkage, and fatigue. There is a certain index relationship between cement strength and anti-erosion properties.
