摘　　要：为了研究旧沥青对无机结合料冷再生稳定料路用性能的影响,按照《公路无机结合料稳定材料试验规程》规定的试验指标,对原路材料进行了材料组成分析,并且通过对几种不同配合比的冷再生材料以及相同配合比的标准稳定碎石的无侧限抗压强度、劈裂强度初步研究,对沥青在冷再生材料中的性能做出了初步分析。To examine impact of used asphalt on road usage performance of inorganic binder,cold recyle stable material, the paper analyzes composition of materials on original road according to testing indexes stipulated in test rules for inorganic binder, stable material, and preliminarily analyzes the performance of asphalt in cold material by means of tentative study of unconfined compressive strength and splitting strength of some types recycle of cold recycle materials in different proportioning and standard stabilized macadams in same proportioning.

关 键 词：旧沥青 抗压强度 劈裂强度 冷再生材料 配合比
