Versions for polymers
Special versions of the Heli-Tank are available for use with modified asphalt. They heat and store either polymer modified asphalt cement (PMAC) premixed at asphalt terminals or asphalt cements that incorporate ground tire rubber (GTR) mixed at the hot mix plant. Both versions maintain the polymer modified asphalt cement at higher than normal temperatures. Pump and piping systems are oversized because PMAC has a higher viscosity than virgin asphalt.

These special versions use motor-driven mixers to keep material in suspension. The mixers are mounted in the top of the tank and are spaced for optimum mixing. The number, size, pitch, location and rotational speed of the impeller blades are key factors in maintaining mixture consistency.
