The Joint Heater is an infrared propane/butane gas burner used on asphalt pavers, assisting in the construction of longitudinal joints. The joint heater will preheat the edge of the previously laid cold lane just prior to placing the new hot mix lane next to it. This approach ensures optimal conditions for a consistent continuous weld of the fresh and previously laid mats, preventing premature cracking of the joint.
The joint heater comprises an aluminum frame with four, six or ten burner heads in stainless steel, and an electronic ignition system that will open the gas flow and ignite the gas in the burners when power is applied
to the circuit. The built-in spark plugs will produce sparks continuously during operation to reignite on flame blow out.
The more burners you have on top of the joint the faster you will get it up to temperature.
Joint heating minimise failures on the joint, resulting in a higher-quality road and allowing faster paving progress and considerable savings for the contractor.
