Sino Howo Asphalt Distributor Tank Truck Road Maintenance Truck Bitumen Spraying Truck
Sino Howo Asphalt Distributor Tank Truck Road Maintenance Truck Bitumen Spraying Truck
The truck's primary role is the precise and uniform spraying of liquid asphalt—which can include hot asphalt, modified asphalt, emulsified asphalt, or cutback asphalt—onto a road surface.
- Tack Coat/Prime Coat: Applying a thin layer of asphalt emulsion to improve the bonding between old and new pavement layers.
- Surface Sealing: Used in chip sealing or fog sealing to protect the pavement from water and oxidation.
- Asphalt Surfacing: Providing the final asphalt layer in road construction.
Intelligent Asphalt Distributor Truck is a machine specially designed for construction and curing of asphalt road surfaces, which is widely applied in operation, such as transport and distribution of high-temperature liquid asphalt, emulsified asphalt and modified asphalt. The operation of the asphalt pump is controlled by hydraulic system and the transmission is stable, enabling safe and reliable operation. Asphalt can be sprayed evenly via the rear spray bar or the handheld spray bar according to the actual construction. Spraying via the rear spray bar is automatically controlled by the computer. The spray rate is under computerized control and is accurate. The asphalt pump and piping use heat transfer oil for heating and thermal insulation. The pipes and nozzles are flushed by compressed air, in order to avoid being clogged. The maximum spray width is up to 6m, and the spraying operation is high-efficiency and easy, with safe and reliable service behavior.

| Component | Common Specifications and Features |
| Chassis | SINOTRUK HOWO (most common models are 4x2 or 6x4 drive). Engine power typically ranges from 290 HP to 371 HP. |
| Asphalt Tank | Capacity: Varies widely, from 4,000 Liters (4m) up to 16,000 Liters (16m). |
| Insulation | Three-layer structure is standard: inner steel tank, a thick insulation layer (50mm-100mm rock wool), and an outer stainless steel or carbon steel skin to maintain the asphalt's temperature (often with a temperature drop of 1.5dEgree |
| Heating System | Heat Transfer Oil: The most common and advanced method uses a diesel burner (often an imported brand like Italian BALTUR or G20) to heat thermal oil, which then circulates through coils in the asphalt tank. This indirect heating prevents the asphalt from coking. |
| Spraying System | Intelligent Control: Many models feature a full computer/PLC (often Siemens) control system with a touch screen in the cab. This system automatically links the asphalt pump speed to the vehicle's ground speed to ensure a precise, consistent spray rate |
| Spray Bar | Foldable Design: Typically a three-section folding bar to achieve a wide working width (4.5m to 6.0m) and a narrow transport width. |
| Nozzles | Equipped with multiple intelligent nozzles (34 to 48 pieces), each controlled by an individual solenoid valve to ensure three-overlapping spray effect for uniform coverage. |
| Asphalt Pump | High Viscosity Gear Pump (model QGB950) driven by a hydraulic motor, designed to handle hot, high-viscosity materials like modified asphalt. |
| Cleaning System | Features a system (often using compressed air and diesel) to flush and clean the asphalt pipeline after use, preventing solidification and blockage. |

The truck's primary role is the precise and uniform spraying of liquid asphalt—which can include hot asphalt, modified asphalt, emulsified asphalt, or cutback asphalt—onto a road surface.
- Prime Coat: Applying a layer of low-viscosity asphalt material (usually cutback asphalt or asphalt emulsion) onto a prepared, non-bituminous base layer (like compacted gravel or crushed stone). This penetrates the base, seals surface voids, and promotes adhesion to the subsequent asphalt layer.
- Tack Coat (Bond Coat): Applying a thin layer of asphalt emulsion (bitumen) between two successive bituminous layers (e.g., between the existing pavement and a new asphalt overlay). This acts as a "glue" to ensure the new layer bonds tightly to the old layer, preventing slippage or delamination.
- Waterproof Layer: Applying specialized asphalt emulsions or modified asphalt as a waterproof barrier on bridge decks or elevated road sections before final paving.
Asphalt distribution truck is widely used in highway construction and highway maintenance engineering. It can be used for the different pavements of upper and lower sealing layer, prime coat, waterproof layer, adhesive layer, asphalt surface treatment, bituminous penetration pavement, and fog sealing layer and other construction. It also can be used for transportation of liquid asphalt or other heavy oils.
