    Abstract

    The general aim of the Finnish CLASS project was to develop pavement materials and subbase structures that are water permeable, and suitable and usable for the Nordic climate. Selected pavement structures were tested in laboratory environment: Their water infiltration was measured at an initial stage, after clogging and after two different cleaning methods. Pavement materials used were pervious concrete (PC), porous asphalt (PA) and concrete blocks with bound and unbound joints. The substructure was the same for every surface: base and subbase layers with a very high void content. The main results were that the permeability was dependent on the surface layer material, and clogging delays substantially the infiltration rate. Cleaning maintenance improved the infiltration capacity.
