摘　　要：通过水泥粉煤灰稳定碎石的无侧限抗压强度、劈裂强度和干缩系数试验研究,分析了粉煤灰掺量对强度和干缩特性的影响及其变化规律。推荐出合适的粉煤灰掺配比例,并进行了实体工程验证,为水泥粉煤灰稳定碎石基层混合料规范编制和推广应用提供了基础数据。By the experimental research on the unconfined compressive strength, splitting tensile strength and shrinkage coefficient of the cement and fly-ash stabilized crushedstones, the strength and shrinkage characteristics of the variation are analyzed. Appropriate blending ratio of fly ash is recommended and the engineering is tested and verified, which can provide basic data for the industrial standards and the application promotion.
