摘要
选择不同二灰剂量、不同集料级配类型、不同龄期的二灰稳定碎石,通过室内无侧限抗压强度、劈裂强度、抗压回弹模量试验,系统分析结合料剂量、集料级配类型和养生龄期等因素对二灰稳定粒料强度特性的影响,获得强度特性的变化规律,可为设计适应黄土地区的高强度抗裂二灰稳定碎石基层提供实用参考。
According to choosing mixtures which are composed of different lime-flyash content and different aggregate gradation, regulations of mechanics capability can be found by series of experiments and analysis about several factors such as binder content, graded style and curing time. Meanwhile, based on these regulations, the gradation and composition of the lime-flyash stabilization aggregate which are satisfied the requires of base course＇s strength can be proposed.
