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…

Convoy: sweep, spray, spread, roll for edge renewal.

An electromagnetic clutch uses an electrical current to engage or disengage mechanical drive between rotating components. It allows auxiliary systems to be controlled without a constant mechanical connection. When energised, a magnetic field pulls friction surfaces together to transmit drive. When power is removed, the drive is released, allowing controlled disengagement and on-demand operation of…
