CLW Asphalt Distributor Bitumen Emulsion Spreading Sprayer Spraying Chip Seal Truck

Equipped with PLC controls and in-cab monitors. The system automatically adjusts the asphalt pump speed based on the vehicle's travel speed to ensure a uniform spray rate (accuracy often within).

Uses high-efficiency diesel burners (e.g., Italian Riello brand) paired with thermal oil circulation to maintain high temperatures and prevent bitumen solidification.

The tanks are typically built with carbon steel and wrapped in 50mm–100mm of rock wool insulation, finished with a stainless steel outer skin to minimize heat loss.

Features a three-section foldable structure with independently controlled pneumatic nozzles. This allows for precision spraying and the ability to avoid obstacles.

Systems generally include both high-pressure air and diesel-flush cleaning to clear the pump and pipelines after operation.

Because CLW is a direct manufacturer, units can be customized with:

• Manual Hand-Spray: A handheld spray gun with a flexible hose for irregular areas or corners.
• Auxiliary Power: Optional Honda or specialized diesel auxiliary engines to power the hydraulic and asphalt pumps independently of the main truck engine.
• Right-Hand Drive (RHD): Available for export markets like Kenya, Uganda, or the Philippines.

CLW Bitumen Distributor trucks are versatile road construction vehicles used for the precise application of asphalt binders. Their usage generally falls into four categories: New Road Construction, Maintenance, Repair, and Logistics.

CLW Bitumen Distributor trucks are versatile road construction vehicles used for the precise application of asphalt binders. Their usage generally falls into four categories: New Road Construction, Maintenance, Repair, and Logistics.

1. Primary Road Construction Applications

The truck is most commonly used to create essential layers between different road materials:

• Prime Coating: Applying a thin layer of bitumen over a non-asphalt base (like gravel or soil) to prepare it for the first layer of asphalt. This seals the base and provides a "key" for the asphalt to stick to.
• Tack Coating: Spraying a thin, sticky layer between two layers of asphalt to ensure they bond together as a single structural unit, preventing sliding or delamination.
• Waterproof Membrane: Used specifically on bridge decks and concrete surfaces to prevent water from seeping into the structure and causing corrosion or cracks.
1. Pavement Maintenance & Rejuvenation

To extend the life of existing roads, the truck is used for "surface treatments":

• Chip Sealing: The truck sprays a uniform layer of hot bitumen, immediately followed by a chip spreader that drops stone chips. This creates a new, skid-resistant wearing surface.
• Fog Sealing: A light application of diluted asphalt emulsion onto an old road surface to "rejuvenate" it, sealing small cracks and preventing the surface from becoming brittle and "raveling."
• Slurry Seal & Micro-Surfacing: Serving as the supply unit for the bitumen binder used in these thin-layer resurfacing techniques.
1. Specialized Repairs
• Pothole Patching: Using the Handheld Spray Gun, operators can manually apply bitumen to the edges and bottom of a pothole to ensure the new asphalt patch sticks permanently.
• Crack Filling: Precision spraying to seal linear cracks in the pavement, preventing water from entering and damaging the road foundation.
2. Logistics & Self-Loading

Beyond spraying, the CLW system is designed for material management:

• Asphalt Transport: Safely moving hot liquid bitumen from a heating station to a remote job site while maintaining the temperature via the onboard burner.
• Self-Suction (Pumping): The truck can use its own pump to suck bitumen from an external storage pool into its tank, or pump it out into another container, acting as a mobile pump station.

• Uniform Spraying: The intelligent control system monitors the truck's speed and automatically adjusts the pump pressure to ensure the spray volume (e.g., 1.0 kg/m 2) remains constant, even if the driver speeds up or slows down.
• Heating & Circulation: To prevent the bitumen from solidifying in the pipes, the truck can "circulate" the hot oil through the spray bar without spraying, keeping the entire system warm and ready for immediate use.
• Cleaning: After work, a "dual cleaning" system uses high-pressure air and a diesel flush to clear the nozzles and pipes, ensuring they aren't blocked by hardened asphalt the next morning.
