Versatile Asphalt Sprayer for Highways, Bridges, and Municipal Paving Projects
This intelligent asphalt distributor is specifically designed for precise surface dressing, chip sealing, and waterproof layer construction. It handles emulsified asphalt, hot asphalt, modified emulsified asphalt, and modified bitumen, making it ideal for highway maintenance, bridge deck paving, tunnel waterproofing, and urban road construction. The triple-overlap spraying system ensures uniform coverage from 0.2 to 4.5 meters wide, with adjustable spray rates from 0.2 to 2.0 kg/m² to meet diverse project requirements.

Heavy-Duty Chassis with Fully Insulated Tank and Smart Spray Rate Control System
Built on a SX1189LA1F1C 4×2 chassis with Weichai 240 HP engine, 4500 mm wheelbase, and 10.00R20 radial tires, this unit features a 10 m³ carbon steel tank with 50 mm rock wool insulation and stainless steel cladding. The hydraulic system includes Rexroth proportional valves, Eaton motor, and QGB680 asphalt pump. The intelligent controller (IP67) links spray rate with vehicle speed via a 10-inch touchscreen, supported by dual Riello burners, full thermal oil heating, automatic cleaning, and a 5KW generator for standalone operation.
