Asphalt Caulking Machine

The asphalt crack sealing machine is a lightweight specialized equipment designed for road crack maintenance. Equipped with an 800L large-capacity asphalt tank and a total vehicle weight of 4495 kg, it meets light-duty specialized vehicle regulations while balancing operational endurance and road mobility. The asphalt tank features a double-layer insulation structure and a dual-heating system (electric heating + auxiliary fuel heating) with a temperature control accuracy of ±5°C, ensuring optimal asphalt application temperature of 160–180°C to prevent clogging.

The machine is equipped with a high-pressure emulsified asphalt pump and a 360° rotatable sealing gun, suitable for crack widths of 5–50 mm, with a sealing speed of 3–5 m/min. A front-mounted high-pressure hot air gun pre-cleans debris from cracks, enhancing asphalt adhesion and extending crack repair life by 2–3 years. The reinforced chassis ensures optimized load distribution, adapting to complex road conditions such as municipal and rural roads without causing damage during operation.

Dual safety systems, including high-temperature warnings and emergency shutdown, are integrated. The control panel monitors temperature and flow rate, enabling a single operator to perform cleaning and sealing tasks. It is widely applicable for preventive crack maintenance on highways, municipal roads, and residential streets, effectively preventing crack expansion and extending pavement service life.
