A storage-stable rubberized asphalt paving pellet can include fines in the core. The core can be an asphalt-based binder at about 70% to about 95% by weight of the core. The asphalt-based binder can include: ground tire rubber from about 15% to about 30% by weight of the asphalt-based binder, and pavement grade asphalt from about 85% to about 70% by weight of the asphalt based binder. The core can include fines at about 30% to about 1% by weight of the core. The shell coating the core can provide the pellet with a maximum dimension of about 1/16 inch to about 2 inches. The shell can include a water-resistant polymer or wax, or a coating of fines. In one aspect, the fines are lime fines or ground asphalt pavement fines. Optionally, the fines can be mineral or rock fines as described herein. |
