The technology of low-carbon Grassed swale based on Porous concrete

In the article,Grassed swale based on Porous concrete(GP),which is a new drain on the highway,are introduced.GP is the drainage facility that constructs by green-growing porous concrete.The article focuses extensively on the election and using ratio of filled material and plants used on the GP,describes the fill method of material and the maintenance of GP.With its many advantages,such as reducing pollution,emission reduction,and virescence,GP will become the core technology of the treatment of highway runoff in the future.
