Dongfeng D9 4x2 500 L Bitumen Road Maintenance Truck

This Dongfeng D9 road maintenance truck carries what a patching crew needs to repair potholes and damaged asphalt from one chassis. An insulated V-shaped hopper keeps asphalt mixture hot on the way to the site, a separate 500 L heated bitumen tank supplies tack coat through a hand spray nozzle, and a hydraulic pickaxe coupling lets the crew break out damaged pavement.

The hopper has a 6,500 L effective volume, 150 mm of insulation and a one-piece straight auger driven by a hydraulic motor to discharge material. Thermal-oil circulation heated by a Liyalu G10 burner keeps the material at working temperature, supported by a 7 kW gasoline generator and an insulated high-viscosity asphalt pump. Controls are in the cab and at a rear auxiliary station. The EQ1185LJ9CDE chassis offers D4.0NS6B195 (195 hp) or B6.2NS6B230 (230 hp) diesel engines with a FAST 8-speed gearbox, Dana axles and a double-layer frame.

The truck measures 7,790 × 2,550 × 2,890 mm on a 4,500 mm wheelbase, with an 18,000 kg gross vehicle weight and a 7,370 kg rated payload, so load the hopper by weight rather than volume when carrying dense mix. It suits city streets, highways and industrial roads where quick, small-area repairs are needed, and body color can be customized.
