Critical Permeability Values of Asphalt Concrete for Field Cores and Laboratory-Compacted Samples

The permeability of asphalt concrete (AC) pavement is affected significantly by the compaction procedure, test procedure, and pore connectivity. However, past studies put no effort to include these factors when determining the critical permeability limit. Also, all the past permeability limits are on the basis of only the correlation between the permeability and air void. This study used correlations of total pore, permeable pore, and moisture damage with permeability of laboratory-compacted and field-collected cores to determine a critical permeability limit. The critical permeability values obtained were 320×10⁻⁵, 100×10⁻⁵, and 100×10⁻⁵  cm/s for field cores, gyratory samples, and linear kneading compacted samples, respectively.
