Joint Performance

Joint heater tf-technologies paving made easy

Eliminate joint failures

The weakest part of an asphalt road is found in the longitudinal joint. On the edge of the mat it is difficult to get a high density and is typically where you see premature cracks.


Paving multiple lanes side by side (echelon paving) to compact the joint while still hot on both sides, is the safest way to ensure high-quality joints. Yet, the need to maintain traffic makes this impossible.

The solution? Heat up the edge of the cold lane with a Joint Heater to mimic echelon paving and increase joint density.

How it works

The Joint Heater is an infrared propane-butane gas burner. Mounted just in front of the screed on the asphalt paver and connected to an appropriate gas source, the Joint Heater will effectively preheat the edge of the previously laid cold lane just prior to placing the new hot lane next to it.

The Joint Heater contains four to 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.
