PERMEABLE HOT MIX ASPHALT FOR AIRFIELD PAVEMENT. REPORT ON AN APPLICATION IN ILLINOIS

The article describes the Hot Mix Asphalt Treated Permeable Subbase (HMATPS) which is a component of the subsurface drainage system. HMATPS collects any free water which may enter the subbase and allows it to drain to edge drains located on the edges of apron and parking lots. In the Willard Airport Project in Illinois, most of the water entering the subbase is expected to penetrate through the pavement surface. Due to site topography, little subsurface water is expected to enter the subbase. In this project, the structural value of HMATPS was assumed to be equal to that of a crushed aggregate base course. Lime modified soil was used to prevent upward migration of fines into the HMATPS. Details are given of the specification and the mix design for the project.
