Asphalt Distributor Truck Spray Bar and Heating Basics

Asphalt Distributor Truck Spray Bar and Heating Basics

• Asphalt distributor trucks carry 5000 to 14000 litres of bitumen on a Sinotruk HOWO chassis, with a heating system, spray bars and a manual gearbox sized for road maintenance and patch work in tropical and arid climates.
• Roads in remote areas with no central bitumen supply that rely on a delivered truck every few days for surface sealing and patching.
• Construction sites where asphalt spraying stops during refilling due to lack of on board heating and storage capacity.
• Contractors using converted tankers that leak or fail to maintain consistent spray pressure at low temperatures.
• Projects where imported distributors have no local support for repair or replacement of spray bar nozzles and heating elements.
• Tanks without internal heating coils that cool too quickly during long hauls, causing bitumen to thicken and block spray lines.
