2 Research questions Is permeable pavements efficient in terms of capturing storm water runoff volume and peak flow in a Danish context? What is the capacity of capturing storm water runoff volume To what extend can peak flow be reduced? What is the carrying capacity? What is the lifespan and means of maintenance to prolong the effectiveness of the pavement? To what extend is the reservoir in the base course fully used? Dias 2
