摘　　要：虽然适量添加一些外掺剂,对再生混凝土路面抗冻性有一定程度的改善,但是对再生混凝土抗冻性影响最大的因素还是再生骨料取代率。文章研究了不同再生骨料取代率对再生混凝土路面抗冻性的影响,为再生混凝土在寒冷地区的推广使用提供依据。Although the appropriate addition of some admixtures can improve the frost resistance of re- cycled concrete pavement to some extent,the biggest factor affecting the frost resistance of recycled concrete is the recycled aggregate replacement rate.This article studied the effect of different recycled aggregate replacement rates on the frost resistance of recycled concrete pavement, which can provide the basis for the popularization and utilization of recycled concrete in cold area.

关 键 词：再生混凝土路面 再生骨料取代率 影响 抗冻性
