中文摘要：

通过将一定量的乳化沥青和粗集料（天然粗集料或再生粗集料）一起进行搅拌,从而改善粗集料表面的黏结性能;在水泥、水、天然砂、粗集料配合比一定的情况下,添加再生橡胶颗粒或再生钢纤维橡胶颗粒,然后通过改变再生粗集料取代率来研究再生混凝土的轴心抗压性能和破坏特征。

英文摘要：

This study presents experiments on mixing a certain amount of emulsified asphalt and coarse aggregate （natural or recycled coarse aggregate）together to improve the surface caking property of the coarse aggregate.As the mixture ratios of the cement,water,natural sand and coarse aggregate are fixed,adding the recycled rubber granular or the steel fiber rubber granular into the mixture.And then the axial compressive performance andfailurecharacteristicsofthesekindsofmodifiedconcretewithdifferentreplacementofrecycledcoarseaggregatebymasswereinvestigated.
