I. Choosing the Right Tools is Key
Melting bitumen isn't something you can do with just any pot! We recommend using a professional bitumen heating tank. These devices have a built-in temperature control system for precise temperature control. If resources are limited, a thick-bottomed iron pot can be used, but please note:
Capacity Selection: Choose the capacity according to your needs. 50L is sufficient for small projects, while 200L or more is recommended for large-scale construction.
Heating Method: Electric heating is safer; for gas heating, ensure good ventilation.
Auxiliary Tools: Prepare a long-handled wooden shovel (to prevent burns), a thermometer (for real-time monitoring), protective gloves, and safety goggles.

II. Temperature Control is Crucial
Melting bitumen is like brewing tea; the wrong water temperature will result in a poor brew:
Ordinary Road Bitumen: 130-150℃ is optimal; temperatures above 180℃ will cause aging.
Modified Bitumen: Requires 160-180℃; melting time is 20% longer than ordinary bitumen.
Heating Techniques: Preheat at a low temperature first, then gradually increase the temperature, ideally by 5℃ every 10 minutes.
Special Reminder: Stir continuously during the melting process to prevent localized overheating! Stir with a wooden shovel in a figure-eight motion, 15-20 times per minute.
III. Three Principles of Safe Operation
Melt melting asphalt may seem simple, but these safety details must be remembered:
Ventilation First: Maintain good ventilation at the work site to avoid inhaling asphalt volatiles.
Fire and Scald Prevention: Keep away from open flames; do not place flammable materials within 3 meters of heating equipment; use long-handled tools when pouring asphalt and maintain personal distance.
Emergency Treatment: Prepare fire extinguishers and first-aid kits. In case of burns, immediately rinse with cold water for 15 minutes and seek medical attention.
Tip: Melted asphalt should be used as soon as possible. It will begin to solidify if left for more than 4 hours, and reheating will reduce its quality!
