Portable asphalt heater units is used to heat and soften the
asphalt pavement with pits, bubble, localized net-shaped cracking,
alligator cracking, covering collapse grounds, heat-joint for
treatment on road.
Using the "blue flame radiation conduction technology". Pwerful
radiation penetration and high efficient thermal raidation; the
heating temperature up to 170 degree and heating depth 5 to 10cm
within 3 to 8 minutes.
