Zusammenfassung:	The invention relates to pitch granules comprising a core made up of a first composition including at least one pitch, said composition having a penetrability at 25°C of 0 to 45 1/10 mm, a ring-and-ball softening temperature (TBA) of 55°C to 175°C, understanding the penetrability as measured according to standard EN 1426 and the TBA as measured according to standard EN 1427, and a layer encapsulating at least one portion of the surface of the core, said layer being made up of a coating composition comprising at least one anti-caking agent. Granules de brai comprenant un cœur constitué d'une première composition comprenant au moins un brai, ladite composition ayant une pénétrabilité à 25°C allant de 0 à 45 1/10 mm, une température de ramollissement bille et anneaux (TBA) allant de 55°C à 175°C, étant entendu que la pénétrabilité est mesurée selon la norme EN 1426 et que la TBA est mesurée 5 selon la norme EN 1427, et une couche enrobant au moins une partie de la surface du cœur, ladite couche étant constituée d'une composition de revêtement comprenant au moins un anti- agglomérant.
