Achieve superior pavement preservation results with the Sinotruk HOWO Synchronous Chip Sealer, a high-performance road maintenance vehicle that simultaneously sprays asphalt binder and spreads aggregate chips. This synchronous technology creates a durable, skid-resistant surface that extends pavement life by 5-8 years.
Built on the reliable HOWO 4x2 chassis with an advanced PLC control system, precision heating, and hydraulic power, this vehicle delivers uniform, high-quality chip seal applications for highways, urban roads, bridges, and rural pavements.
The synchronous sealer solves traditional chip seal problems by spraying asphalt and spreading aggregate simultaneously, ensuring immediate embedment and optimal adhesion. This creates a strong mechanical bond that resists raveling, delamination, and moisture damage.
Key Features
Proven HOWO 4x2 Chassis: Renowned for durability, reliability, and excellent load-carrying capacity with powerful diesel engine and stable suspension
Synchronous Spraying & Spreading Technology: Simultaneous application ensures immediate embedment and optimal adhesion, eliminating separate passes
Large-Capacity Insulated Asphalt Tank: High-density insulation with efficient diesel burner heating system and automatic temperature control up to 180°C
High-Capacity Aggregate Hopper & Precision Spreader: Hydraulically driven with variable-speed conveyor and wide spreading auger for uniform coverage
PLC Automatic Control System: User-friendly touchscreen interface for precise adjustment of spray and spread rates with real-time monitoring
Reliable Hydraulic Power System: PTO-driven hydraulic system with proportional controls for smooth, precise operation
Efficient Heating & Insulation System: Automatic temperature control with high-density insulation to minimize heat loss and reduce fuel consumption
Dual Control Stations: Operational flexibility with both in-cab and rear platform control stations for optimal visibility
Wide Range of Applications: Suitable for chip seal, slurry seal, micro-surfacing, tack coat, and bridge deck waterproofing
Applications
Highway Chip Seal & Pavement Preservation: Extend pavement life with durable, skid-resistant surfaces
Asphalt Overlay Tack Coat: Ensure proper bonding between existing pavement and new asphalt overlay
Bridge Deck Waterproofing: Apply uniform waterproofing membranes to protect structural elements from moisture damage
Rural Road Surface Treatment: Improve surface texture and skid resistance on low-volume rural roads
Parking Lot & Industrial Pavement Sealing: Seal and protect parking lots, industrial yards, and other paved areas
