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…

Guidelines for storing emulsion (temperature, turnover).

Renewing worn edge lines with overlay.

Device adjusting binder pump speed electronically to maintain target application rate. Essential for modern variable-speed surface dressing rigs.

Time until emulsion becomes tacky and trafficable.

Longitudinal white thermoplastic line at carriageway edge for guidance.

Charge-assisted paint application for adhesion.

Gauge showing binder-pump outlet pressure at the control station. Allows fine adjustment to achieve correct nozzle flow.

Rule for overlap of edge lines with bays.
