(57) A lime pellet for use in asphalt applications can include lime fines and an asphalt-compatible binder. The pellet is characterized as having a rigid structure with a dimension greater than about 1.5 mm and being compatible with a hot mix asphalt so as to dissolve in liquid asphalt. Optionally, the binder is characterized by having less than about 50 % by weight of total binder being sulfur, or the pellet is characterized by having lime in an amount of at least 31 % by weight, or being storage-stable and agglomeration resistant. The pellet is manufactured by mixing the lime fines with the asphalt-compatible binder and forming pellets therefrom. The pellets are useful for conditioning an end product of hot mix asphalt during the manufacture of such an asphalt. The method of conditioning includes providing the lime pellet, and mixing the lime pellet with a hot mix asphalt ingredient, wherein the ingredient is at least one of an aggregate or asphalt cement. Additionally, the lime pellets can be used for bonding a first asphalt layer with a second asphalt layer by being deposited therebetween.
