Product Introduction
The XLY1300 is a dedicated, high-performance asphalt crushed stone synchronous sealing machine, rather than a traditional paver. It is the core equipment for preventive maintenance of roads and the construction of stress absorption layers on newly built roads.
Product Advantage
1. "Synchronization" technology: This is the core of the device. Asphalt and crushed stones reach the road surface almost simultaneously. The crushed stones can be more deeply embedded in the asphalt film, forming a stronger mechanical interlocking structure, and the sealing effect is more durable.
2. High-precision control system
Intelligent control: It adopts a CAN bus control system with high integration. The operator can precisely set and adjust all parameters such as the amount of asphalt sprayed, the amount of crushed stone spread, and the spread width in the cab.
One-click operation: It features one-click start and stop functions, ensuring a high degree of automation in the spreading operation and reducing human errors.
3. Even spreading ability
◦ Asphalt system: It adopts a multi-nozzle design and is equipped with pneumatic or hydraulic spraying systems to ensure uniform asphalt spraying and good atomization effect.
◦ Stone system: It adopts a structure of double-screw distributor + hydraulically controlled spreading roller to ensure the uniform distribution of crushed stones in the width direction.
4. Large-capacity silos: A 13m³ asphalt tank and a 15m³ stone silo ensure the continuous operation capacity of the equipment, reduce the frequency of mid-process material addition, and improve construction efficiency.
5. Strong power and chassis: Usually equipped with heavy-duty truck chassis, it offers powerful performance and is suitable for relocation and operation in various construction road conditions.

Product Uses
• Road preventive maintenance: Apply synchronous sealing layers on well-structured road surfaces to seal water, prevent slipping and wear, and delay the occurrence of diseases.
• Road restorative maintenance: Addressing minor defects such as grid cracks, crazing, aging of the wear layer, and decline in anti-skid performance on the road surface.
• New road construction: As a lower seal layer or stress-absorbing intermediate layer (SAMI), it enhances interlayer bonding and prevents reflective cracks.
• Bridge deck waterproofing layer: Construction waterproof bonding layer.
Product Operate Guide
The XLY-1300 is a large-scale synchronous sealing machine, mainly used for road maintenance. Before operation, it is necessary to check the asphalt, stone system and pipelines to ensure there is no blockage. During construction, parameters such as the amount of spreading and the width can be set through the intelligent control terminal. The traveling speed of the equipment must be matched with the pump speed to ensure that the asphalt and the stone are evenly and synchronously spread. After the operation, the asphalt pipeline and the spreading roller should be cleaned immediately to prevent solidification. Operators must undergo professional training and strictly abide by safety regulations.
FAQ
A: It is not a traditional asphalt concrete paver, but a high-performance asphalt gravel synchronous sealing machine. Its function is to simultaneously spray asphalt binder and spread crushed stones, mainly used for road preventive maintenance and stress absorption layer construction, rather than laying a continuous asphalt mixture surface layer.
What are the advantages?
A: "Synchronous" means that the asphalt spraying and crushed stone spreading are completed at the same moment. Its core advantage lies in the fact that the crushed stones can be instantly embedded into the high-temperature asphalt film, achieving the deepest embedding degree and the strongest adhesion, forming an extremely durable wear layer. The waterproofing, anti-slip, and crack spread prevention effects are significantly better than those of step-by-step construction.
A: To ensure uniformity, the following must be achieved:
1. Parameter setting: Precisely set the asphalt spraying volume and crushed stone spreading volume per unit area in the control system.
2. Constant-speed operation: The equipment must maintain a constant and appropriate working speed, which is the key to uniformity.
3. System maintenance: Ensure that the asphalt nozzles are not clogged, the gaps between the spreading rollers are uniform and free from wear.
A: Key preparatory work includes:
• Material preparation: The asphalt needs to be heated to the specified temperature and maintain fluidity; The crushed stones should be clean, dry and of a single specification.
• Equipment inspection: Thoroughly inspect whether the asphalt system, airway, hydraulic system, and spreading system are functioning properly and free of leakage.
• Parameter calibration: Before the official construction, the spraying amount needs to be calibrated and tested for spraying to ensure accuracy.
A: It must be cleaned up immediately! After the operation is completed, diesel or special cleaning liquid should be used to circulate and clean the asphalt pipelines and pumps, thoroughly removing the residual stones in the spreading system to prevent asphalt from solidifying and components from getting stuck. This is the lifeline for the long-term normal use of the equipment.
A: First, reverse circulation flushing or manual unblocking should be carried out. Prevention is better than cure. The most crucial thing is to conduct a thorough cleaning after each operation and carry out regular deep maintenance on the system.
