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 ° 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 .
