A process for preparing a homogenous asphalt composition including the steps of introducing asphalt medium into a reactor vessel; introducing whole tire rubber granules into the asphalt medium to form a mixture of the asphalt medium and the granular whole tire rubber; circulating a portion the mixture into a bottom portion of the reactor vessel through jet spray nozzles; and recirculating the mixture at 500 DEG F. through the vessel until the whole tire rubber is completely integrated into the asphalt medium and a stable, homogeneous asphalt composition is formed. The incorporated asphalt composition preferably includes about 10-20% whole tire rubber and about 80-90% asphalt medium. |
