The present invention relates to an asphalt product that comprises an asphalt component and a plurality of pellets comprising a mixture of a ground tire rubber and an elastomeric polymer, where the density difference between the asphalt component and the plurality of pellets is less than 10%. The present invention further relates to a pellet comprising a ground tire rubber (“GTR”) and an elastomeric polymer mixed with the GTR, where the GTR has a density of less than 1.12 g/cm.sup.3. Also disclosed are methods of producing improved asphalt and paving a surface.
