Permeability test of pervious concrete in different rainfall

Pervious concrete as an environment-friendly road pavement material in urban roads has been widely applied. By designing new permeability testing apparatus, simulated rainfall detection different rainfall pervious concrete permeability test methods on different rainfall on pervious concrete permeability. Research shows that: 1. A new kind device of permeability testing can accurately reflect the pervious concrete work status.2.The permeation which is measured by being simulated rainfall is lesser than invariable water head, and the deviations of these enlarged in the wake of the porosity´s increasing.
