Common rapid set emulsion grade for dressing.

Written procedure for isolating vehicle electrics before repair. Part of standard safe-system-of-work documentation.

Fine filter positioned before the spray bar inlet. Prevents nozzle blockages caused by coagulated binder or debris during surface dressing.

Chart listing fuse ratings and circuit assignments. Stored inside the cab fuse box for quick reference by operators.

Valve isolating the pump from the main binder circuit. Allows maintenance without draining the full tank contents.

Valve block combining electric control with hydraulic actuation.

Pump transferring surplus emulsion back to the main tank. Prevents wastage and maintains consistent temperature during start-stop work.

Hydraulic arm that extends the side broom beyond the vehicle width. Useful for cleaning channels and gullies along kerbs and barriers.

Solenoid valve operating spray sections via air actuation.

An emulsion stability test is used to assess whether a bitumen emulsion remains uniformly mixed over time without separating. Stability is important to ensure the material performs predictably during spraying and bonding. The test checks resistance to breaking or separation under controlled conditions, providing confidence that the emulsion will remain consistent during storage, transport, and…
