Abstract


In recent years, it is more and more difficult to mine the natural aggregate, such as gravel. Through the comparative analysis of the material characteristics of recycled aggregate and natural gravel, such as water absorption, bulk density and crushing index, the experimental study shows that recycled aggregate is suitable for the construction of sponge city, and further introduces the structure and application advantages of the bioretention in sponge city, where recycled aggregate from construction waste is used. It is proposed that its construction technology, process, key points of construction quality control and subsequent maintenance management measures can provide reference for the application of recycled aggregate in bioretention in sponge city.
