Abstract: In this study, test procedures are compared and discussed with respect to their suitability for porous asphalt optimization and for development of improved mix design. Several industry standard tests namely wheel tracking, indirect tensile, interlayer shear strength, Cantabro and water permeability were carried out to compare performance related proper-ties of both theoretically and empirically designed porous asphalt specimens. The specimens were produced using an improved theoretical mix design approach for porous asphalt. It is based on a new packing theory for aggregate grading optimization, reducing the post compaction effects on the pavement under traffic. In this international co-operative research project between JHRI and EMPA, porous as-phalt specimens produced by the new mix design method were compared to both Swiss and Japanese Standard mixes from conventional empirical mix designs. Different tests concerning both durability and functional properties of porous asphalt were carried out. The results of this ongoing research indicate that the new method leads, in many cases, to porous asphalt mixes with superior quality as compared to traditional standard mixes. In addition it is shown that the different test methods applied in this study generally lead to comparable results.
