Au Brésil, le transport routier est le principal moyen de se déplacer et la grande majorité des routes sont revêtues de béton bitumineux. La couche de frottement poreuse (CFP) se caractérise par une granulométrie ouverte avec une faible quantité de fines et un pourcentage élevé de volume de vide. Cette étude a caractérisé les granulats de granit et les liants bitumineux AMP 55/75 et a vérifié l’aptitude de ces constituants à produire une couche de frottement poreuse. Les étapes méthodologiques de la recherche correspondent à la caractérisation physique des granulats, à la caractérisation rhéologique du liant et à l’analyse du dosage de l’asphalte à l’aide de paramètres volumétriques et de la résistance à la traction. Les données de cette étude se sont avérées cohérentes avec les normes adoptées en termes de caractérisation des granulats et d’obtention des volumes de vides, d’affaissement et de ruissellement. Les valeurs obtenues pour la résistance à la traction n’étaient pas conformes à la norme établie. Une suggestion est d’effectuer une analyse microstructurale des matériaux utilisés.
