Provide users with cost-effective synchronous gravel sealing trucks
Road maintenance vehicles demonstrate significant comprehensive advantages in road construction and maintenance, manifested in the following aspects:
1, High construction efficiency of road maintenance vehicles
Synchronous operation capability: It can spray asphalt binder and spread crushed stone synchronously in the same process, without the need for step-by-step operation, shortening the construction period and reducing process connection errors.
Automated control: Using full hydraulic drive, computer touch screen operation, and CAN bus control technology, automatic adjustment of construction speed and material quantity is achieved, reducing manual intervention.
Rapid opening of transportation: The construction process is simplified, and after completion, it can be quickly opened to traffic, reducing the impact on transportation.
2, Excellent construction quality of road maintenance vehicle
Enhanced waterproof and wear-resistant properties: The synchronous combination of asphalt and crushed stone forms a dense wear layer, significantly improving the waterproof, anti-skid, and wear-resistant properties of the road surface.
High uniformity of bonding: The interval between asphalt spraying and gravel spreading is short (such as within 1 second), ensuring a tight bond between the two and reducing aggregate loss.
Strong adaptability: It can accurately adjust the laying parameters, adapt to different terrains (such as highways, mountainous roads) and climate conditions, and ensure construction stability.
3, Road maintenance vehicle has outstanding economic efficiency
Cost savings: Synchronous construction reduces equipment investment and manpower requirements, with low material waste and overall costs lower than traditional processes.
Low maintenance costs: By extending the service life of roads and reducing the frequency of periodic maintenance, long-term maintenance costs are significantly reduced.
4, Road maintenance vehicle environmental improvement
Reduce pollution: Closed spray systems reduce dust, and the use of environmentally friendly materials further reduces the negative impact of construction on the environment.
Energy conservation and consumption reduction: The thermal oil heating system and asphalt thermal regeneration technology improve energy utilization efficiency and reduce energy waste.
5, Road maintenance vehicle technology innovation advantages
Equipment intelligence: equipped with video surveillance, angle sensors, etc., to achieve precise control of the entire construction process.
Multi functional applicability: Supports the laying of various asphalt media (such as emulsified asphalt, modified asphalt) and different specifications of stone materials, meeting diverse needs.
In summary, the gravel sealing truck has promoted progress in the field of road construction in multiple dimensions such as efficiency, quality, cost, and environmental protection through technological innovation and process optimization.
