In-Situ Permeability of the Outermost Layer of Asphalt and Cement Concrete Road Materials
A permeability cell was developed by applying Carman and Klinkenberg principles to measure the permeability of a porous medium to gas. The method applied concentrates gas flow on a better well-defined area on the surface of the material tested. Both the cell and the calculations used are explained in detail in this paper. The permeability was measured on three hot-mix asphalt mixes (HMA), which were compacted into 125x400x600 mm3 slabs in order to allow the simulation of in-situ conditions. The permeability cell test results show a higher variability in the permeability values of HMA as compared to those obtained from cement concrete measurements. The permeability to gas, when transformed to water permeability, found in this research is comparable to the results found in the literature.
