CORRELATION BETWEEN THE LABORATORY AND FIELD PERMEABILITY VALUES FOR THE SUPERPAVE PAVEMENTS

This study investigates the effects of permeability on the performance of Superpave pavements. Laboratory and field permeability tests were conducted on different Superpave mixes with 19 mm and 12.5 mm nominal maximum aggregate sizes and coarse and fine gradations. The correlation between the laboratory and field permeability values was studied in order to assess whether the field permeability values could be estimated during the mixture design process so that mix design could be adjusted depending on the degree of permeability desired. Findings revealed a significant difference between the laboratory and field permeability values, with field permeability values being consistently higher than the laboratory permeability values. The mat tearing by heavy breakdown roller significantly increased the field permeability values. No statistical correlation was found among the field permeability, the laboratory permeability and the percentage air voids of the laboratory-compacted specimens.
