AI Technical Summary
In existing technologies, asphalt pavement heating processes suffer from uneven heating and aging in other areas, which restricts construction quality and efficiency.
Design an asphalt heating device for asphalt pavement maintenance. The device uses an indirect heating method with a contact plate. The heat is first heated by the contact plate and then conducted through the plate, avoiding direct contact between the open flame and the asphalt, thus achieving uniform heating.
This method achieves uniform heating of the asphalt surface, avoids thermal stress differences and aging phenomena, and improves construction safety and repair quality.
