    Key Features:

    1. Synchronization Mechanism: The truck features a sophisticated synchronization mechanism that coordinates the application of the sealing material with the forward movement of the vehicle. This ensures a consistent and uniform application across the entire gravel surface.
    2. Spraying System: The truck is equipped with a precision spraying system that evenly distributes the sealing material onto the gravel. This system can be adjusted to control the application rate, allowing for optimal coverage and minimizing waste.
    3. Aggregates Distribution: Some synchronous gravel sealing trucks also have the capability to dispense additional aggregates like small stones or chips onto the wet sealing material. This creates a textured surface that enhances traction and durability.
    4. Tank and Mixing System: The truck features a large tank for storing the sealing material, which is often heated to maintain its fluidity. A mixing system ensures that the sealing material remains well-blended and ready for application.
    5. Control Cabin: The driver’s cabin is equipped with advanced controls that allow the operator to regulate the spraying system, synchronization mechanism, and other parameters. This ensures precise application according to the specific requirements of the road or surface being treated.
    6. Navigation and Tracking: Some models may incorporate GPS or other navigation technologies to ensure accurate coverage and track the areas that have been treated. This helps prevent overlaps and missed sections.


    • Prolonged Lifespan: The synchronous gravel sealing truck significantly extends the lifespan of gravel surfaces by protecting them from the effects of weather, traffic, and erosion.
    • Reduced Maintenance: Treated surfaces require less frequent maintenance, saving both time and resources.
    • Enhanced Safety: The addition of aggregates to the sealing material improves surface grip, reducing the risk of accidents due to skidding.
    • Cost-Effectiveness: Long-term cost savings are achieved through decreased repair and maintenance expenditures.

    In conclusion, a synchronous gravel sealing truck is an innovative solution for maintaining gravel surfaces by applying sealing materials in a synchronized and controlled manner. This vehicle combines advanced technology with efficient design to improve the durability, safety, and overall quality of gravel roads and areas.
