What equipment and heating systems are required to safely spray bitumen emulsion from truck-mounted units?
Truck mounted systems need controlled pumping, metering, and a spray bar designed for emulsions, plus safety controls. Heating is not always required for standard emulsions, but insulated tanks and lines can help maintain viscosity and prevent cold weather issues. For polymer modified or high viscosity grades, gentle heating and temperature monitoring may be needed to stay within product limits without destabilizing the emulsion. Essential equipment includes filtration strainers, flow meter, pressure regulation, calibrated nozzle set, recirculation for uniformity, and anti drip valves. Safety requires spill containment, emergency shutoff, PPE, and clear cleaning procedures that do not contaminate future loads.
