Synchronous grade sealing truck that meets user customization needs
As the core equipment for road construction and maintenance, the advantages of Synchronous Gravel Sealing Truck mainly lie in the following aspects:
1, Efficiency and Cost Advantages of Synchronous Gravel Sealing Truck Construction
Efficient integrated operation: synchronously completing asphalt spraying and gravel spreading, reducing the process time of traditional multi equipment collaboration, and significantly improving construction speed.
Outstanding economy: Integrated design reduces equipment procurement and maintenance costs; The sealing technology itself requires less material, and the comprehensive maintenance cost is only 1/3 to 1/2 of traditional processes.
2, Synchronous Gravel Sealing Truck Technology and Quality Advantages
Material bonding firm: The interval between asphalt and crushed stone landing is short (≤ 1 second), ensuring full penetration and squeezing of both, forming a high-strength wear-resistant layer.
Precise control of spraying: Fully automatic computer control achieves stepless adjustment of spraying amount and width, with an error controlled within ± 2% and a uniformity of over 95%.
Improve road performance:
Waterproof and crack resistant: Form a dense waterproof layer to reduce diseases such as mud pumping and potholes caused by water infiltration;
Anti slip and wear-resistant: The surface structure depth increases by 30%~50%, the friction coefficient increases by 20%~30%, and the driving safety in rainy weather is significantly improved;
Extend lifespan: Repair defects such as ruts and mesh cracks, and extend the service life by 3-5 years compared to traditional techniques.
3, Synchronous Gravel Sealing Truck Operation and Security Advantages
Intelligent control: equipped with a touch screen operating system, CAN bus technology, and multi angle camera monitoring to reduce the risk of manual errors.
Environmental protection and safety design: The thermal oil circulation heating system can save more than 30% energy, and the forward construction reduces the probability of personnel coming into contact with high-temperature asphalt; Anti collision spray structure reduces equipment collision damage rate.
4, Adaptive and Flexible Synchronous Gravel Sealing Truck
Widely applicable scenarios: It can be used for both preventive maintenance of highways (spray rate of 1.5-2.5 kg/m ²) and as a surface layer for low-grade highways (spray rate of 2.5-4.0 kg/m ²).
Precise targeted repair: supports targeted repair of local diseases, reducing material waste by 15% to 20%.
Through mechanization, intelligence, and technological innovation, this equipment has achieved comprehensive breakthroughs in construction efficiency, quality, and economy, becoming a technological benchmark for modern road maintenance.
