The Design and Case Study of Pervious Concrete Materials
This study is mainly focused on the design and application of pervious concrete material to pavement and growing plant. The test results show: 1. Addition of fine aggregate obtains better binder quality. 2. Both small aggregate size and good aggregate gradation improve strength, but reduce void ratio and permeability. 3. A data bank of the relationship of the strength, the void ratio and the permeability of pervious concrete was built. 4. A practice case study of pavement demonstrates excellent permeability comparing to the local code and good quality as well as grass growing normally.
