Abstract: The aggregate gradation of pervious asphalt concrete is studied to maximize the interconnected void contents and the permeability. The arrangement of the aggregate gradation is chosen from 3 aggregate maximum sizes and different gaps in the gradation. The binder contents have been getting with the aid of Marshall test, considering the functions: the void content, the interconnected void content and the Cántabro test. The interconnected void contents are defined from the Marshall specimens. Plates have been made to evaluate the rutting, the permeability; three plates for each mixture, according the French standard with the tire machine LPC. The test results showed that the choice of the gap let the pervious asphalt concrete with percentage of interconnected void higher than 25% and with speed of drainage higher than 7 cm/s in the permeability test. The values of the loss in the Cántabro test were smaller than 25% and the rutting values were smaller than 10%. The study showed that it is possible to obtain pervious asphalt concrete with interconnected void content close to 25% controlling the gap in the aggregate gradation. And this mixture is able to remain stability of rutting and of aggregation.
