    Abstract

    Laboratory testing was conducted to determine the effects of aggregate gradation and asphalt content on the stability and permeability of open-graded asphalt concrete. Test results indicate that permeability increases and stability decreases as the aggregate gradation becomes more open-graded, that is, includes less of the smaller sized particles. Also, permeability decreases as asphalt content increases whereas maximum stability occurs at an optimum asphalt content. Open-graded asphalt concrete was installed in the field for a porous pavement parking lot. The pavement has been serviceable for over two years, including exposure to winter conditions.
