Abstract: Through measurement of the physics property,mixture ratio design and the best moisture content of mixture of cement and red mud stabilized graded crushed stones raw material,the characteristics of cement and red mud stabilized graded crushed stones are analyzed from several aspects: unconfined compressive strength,splitting tensile strength,ultrasonic method used to measure modulus of elasticity,compression rebound modulus,frost resistance and solidified mechanism.The results of study show that: every function of mixture with red mud is better than that without adding the red mud;and after synthesizing other lab test results,the best volume range of adding red mud into mixture is determined as 10%~16%.

Key words: cement stabilized graded crushed stones, red mud, performance study, road base, construction materials

摘要： 通过对水泥赤泥稳定级配碎石混合料原材料的物理性能、混合料最佳含水量的测定以及配合比设计,从室内无侧限抗压、劈裂强度、弹性模量、室内回弹模量、抗冻性及固化机理几个方面,分析研究了水泥赤泥稳定级配碎石的特性。研究结果表明:掺加赤泥的混合料的各种性能均优于未掺加的混合料,根据各室内试验结果最终确定了混合料中赤泥的最佳掺量范围为10%~16%。
