Heatec Ground Tire Rubber (GTR) system can blend up to 20% ground tire rubber. This view shows the three tanks, asphalt booster heater, hopper, electric generator, and hot oil heater. |
|
|
Ground Tire Rubber (GTR) blending system has become standard equipment for the State of Florida (USA). |
|
|
|
|
|
|
|
|
Typical production rate is 90 gallons per minute. The system's standard asphalt booster heater outputs 2 million Btu per hour. |
|
|

The system's standard hot oil heater outputs 700,000 Btu per hour and is mounted on the gooseneck. The system shown here is used in the State of South Carolina (USA). |
|
|
The system's control panel houses the variable-speed controls for the auger and asphalt fill pump. It also houses controls for both heaters, the mixers in the tanks, and the chain hoist for loading bags of rubber into the hopper. |

| Portable ground tire rubber system in Florida. This view shows the bag loader in its extended position above the hopper. |
|
Close-up view of the system's bag loader and chain hoist.
|
|
|
|
|
The system's chain hoist and bag loader are designed to raise bags of ground tire rubber like these above the hopper. The operator then pulls the drawstring on the bag, dumping its contents into the hopper. |

|
Storage tank for the continuous-process system. |
|
|
|
|
|
|
|
Other configurations of batch process systems are available. The system shown here includes a 500-barrel storage silo for ground rubber, 6000-gallon mixing tank, and 20,000 gallon Heli-Tank portable asphalt tank. |
|
Vertical storage tanks provide optimum mixing, heating and storage for rubberized asphalt. The vertical configuration allows only a small surface area of the mixture to contact air, minimizing oxidation. |
|
|
|
|
Heatec Heli-Tank portable asphalt tank offers ideal storage for asphalt-rubber at portable plants. Available with mixers specifically designed for storing rubber-asphalt and PMAC. Includes hot oil heater and heating coils. The TriTec heater on the Heli-Tank RR (shown) can easily produce the extra heat required for modified asphalt, in addition to heating other plant components. |
