Full Sized Heaters

The highly efficient infrared heaters can soften 2.5" of surface course asphalt to temperatures of 220°F in 5-10 minutes. This enable scarification, re-leveling and compaction without burning the surface of the asphalt. With up to 16 independent heat zones the operator is able to vary patch sizes by simply turning the heaters off that are not required. This reduces propane costs and time required to complete the repair. The HDE Asphalt Patchers have been used successfully in northern climates where paving becomes a problem in colder months with ambient temperatures below specifications set out by the agencies. If asphalt cools too quickly before proper compaction, problems such as lack of bond, raveling, non-uniform consolidation and rutting, high moisture penetration and increased cracking may occur. A contractor can avoid costly scheduling delays waiting for paving approval on ambient temperatures, and improve quality by using an HDE Infrared Asphalt Patcher to per-heat the base asphalt prior to surface course application
