ABSTRACT:
A modified asphalt and method for making the same is characterized by the addition of a partitioning agent to a polymer modifier material such as synthetic rubber to prevent reagglomeration of the rubber. The partitioning agent reduces the time required to disperse the modifier material in asphalt to be modified and also reduces the viscosity of the modified asphalt so that the modified asphalt is easier to handle.
