  • PERMEABLE TRAFFIC BEARING STRUCTURE
    Publication number: 20130045049
    Abstract: A traffic bearing structure with a permeable pavement includes a subgrade, a base positioned on top of the subgrade, and a wear surface positioned on top of the base. The base includes aggregate compacted in a single lift, where the aggregate in the base includes different sized particles mixed together. The wear surface includes a permeable pavement. The particle size distribution of the aggregate in the base is selected to provide adequate stability and permeability for the permeable pavement.
