Synchronous grade sealing truck with five-star commercial reputation
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.
