Asphalt Crack Sealing Machine Sealcoating Asphalt Road Seam Filling Seal Coating Machine Model GFJ-100

100L Road Crack Sealing Machine

The 100L Road Crack Sealing Machine (Model GFJ-100) is a professional road maintenance machine designed for the efficient heating, melting, and application of crack-sealing materials used in asphalt and paved surfaces. With a 100-litre hot-melt kettle, integrated thermal-oil heating system, automatic temperature control, and electronically controlled material pump, the machine provides controlled and consistent crack-sealing operations.

The machine is designed for improved heating efficiency and reliable material delivery, with a solid-liquid separation system helping to minimise blockages between the hot-melt kettle and pump chamber.

Key Features

100L Material Capacity – Equipped with a 100-litre hot-melt kettle for continuous crack-sealing operations.

Rapid Heating – Heating time of approximately 30–40 minutes.

Wide Temperature Range – Temperature can be controlled from 60°C to 290°C.

Automatic Temperature Control – Intelligent digital temperature controller maintains a consistent operating temperature.

Efficient Material Delivery – Electronically controlled pump provides adjustable and controlled material delivery.

8–15 L/min Discharge Capacity – Provides a controlled flow rate for efficient crack sealing.

Thermal-Oil Heating System – Features a 30L thermal-oil capacity for uniform and efficient heating.

Solid-Liquid Separation – An automatic separator between the hot-melt kettle and pump chamber helps prevent material blockage.

Imported Diesel Burner – Equipped with an Italian Riello 445T1 diesel burner for efficient combustion and controlled heating.

Heated Discharge Hose – Includes a 5-metre electric-heating discharge hose with automatic temperature control.

Safety Protection – Incorporates safety valves and a constant-pressure feeding system.

Flexible Mobility – Can be operated by hand pushing or towing, depending on site requirements.

Technical Specifications

The machine's core specifications, including capacity, heating time, temperature range, discharge rate, dimensions and weight, are provided in the supplied datasheet.

Heating & Material Delivery System

The 100L hot-melt kettle is equipped with a thermal-oil jacket and safety valve system designed to provide faster and more uniform heating of the sealing material. The electronically controlled material pump provides adjustable constant-temperature and constant-pressure delivery, while the full-cycle safety valve supports consistent material output.

The system also incorporates a 5-metre heated discharge hose, allowing the operator to apply the heated crack-sealing material directly to road cracks while maintaining controlled temperature along the discharge path.

Applications

The machine is suitable for road and pavement maintenance applications, including:

Asphalt road crack sealing

Road surface maintenance

Pavement repair

Parking-area maintenance

Industrial and commercial paved areas

Municipal road maintenance

Preventative pavement maintenance

Product Summary

The GFJ-100 100L Road Crack Sealing Machine provides a compact and efficient solution for professional pavement maintenance. Its 100L capacity, 60–290°C temperature range, automatic temperature control, heated discharge hose, adjustable material pump and solid-liquid separation system make it suitable for controlled and continuous road crack-sealing operations.
