Porous Pavement Increases Storage Area at Portland Marine Terminal

This article describes how engineers used porous asphalt pavement to cover nearly 35 acres of terminal six at the Port of Portland, Oregon. The traditional method of managing storm water would require treating and releasing it into nearby Columbia River. By using porous pavement it was not necessary to construct an outfall to the river, which eliminated the need to acquire time-consuming permits. This, in turn, sped up construction time and was environmentally beneficial. To prevent the infiltration bed from compacting, the general contractor used geotextile fabric and coarse aggregate to build a working surface. In addition, about three acres of the site was to be used for loading vehicles onto trucks, requiring a thicker structural section and conventional impervious asphalt pavement. Engineers graded the site in such a way that runoff was directed to sections covered with porous pavement or vegetated swales.
