HDE's revamped asphalt maintenance trailer
Heat Design Equipment (HDE) was displaying updated versions of two of its successful products at Conexpo: the HDE 750 2TMT asphalt maintenance trailer and the HDE JMH 500-PA asphalt joint heater.

The asphalt maintenance trailer heats up and softens an area of asphalt, allowing it to be reworked and repaired. According to HDE, the infrared heaters can soften the top 60mm of asphalt to the original mixing temperatures in between five and 10 minutes.

“A lot of municipalities like this because they can hook it up to their trucks,” said Bob Kieswetter, HDE president. “Using this they can reheat the deteriorated area of asphalt, add new material and recompact in 20 minutes.”

HDE’s longitudinal joint heater attaches to pavers to heat the cold joints before the next lane of asphalt is placed. Infrared heaters reheat the uncompacted edge of the lane, allowing the contractor to recompact the area and meet joint compaction specifications.

“When you pave a lane, you don’t get compaction at the edge of the lane,” explained Kieswetter. “Airports require you to cut that edge off. Road agencies don’t require you to do that, which can lead to a 35% reduction in life.”
