Pothole Patching Crews: Short-Duration Works Done Safely

Pothole patching traffic control has to protect a crew that stops, works and moves dozens of times a shift. Choose the arrangement for each road from the patching method, traffic speed and volume, sight distance and the time spent at each hole. Use mobile or short-term arrangements only while the work genuinely stays brief and low impact.

Patching crews rarely get the planning attention of a big resurfacing job, yet they spend more time on foot in live lanes than almost anyone else in road maintenance. Each repair is short, but the exposure adds up, and the hazard is often in the wheel path, right in the middle of the lane. This guide looks at how to plan patching runs that are both productive and safe.

Why pothole patching is its own traffic problem

Three features make patching different from a normal lane closure.

• Many stops, each brief. A crew can attend many defects in a shift. Every stop means slowing, positioning the truck, stepping out, working and leaving. The set-up and pack-down cycle is repeated far more often than on any static job.
• The hazard is in the traffic path. Potholes form where wheels run. Repairing one usually means occupying part of a live lane, not the shoulder.
• The programme is reactive. After heavy rain, defect numbers jump and the backlog grows. That pressure tempts crews to cut corners: one more patch without moving the truck, a quick dash across the road, signs left in the ute because "we will only be a minute".

The Austroads Guide to Temporary Traffic Management deals with static worksites, mobile works and short-term low-impact worksites in separate parts. Patching can fall into any of them depending on the method and the road, which is why the method has to be decided before the arrangement.

Match the traffic arrangement to the patching method

Different repair techniques keep a crew at a defect for very different times and need different space. Use this table as a planning prompt; the approved traffic guidance scheme (TGS) and your state's requirements decide the actual arrangement.

The jet patcher is a good example of how method changes risk. With the operator working from the cab or a boom, foot exposure falls sharply, and the work can move along a road as a mobile operation. A saw-cut reinstatement is the opposite: the crew may be at one location for an hour or more, and an open cut is a hazard in its own right. Treating that as mobile work because the crew is "the patching crew" is a common mistake.

Mobile, short-term or static: making the call

Our comparison of mobile and static traffic management explains the general principles. For patching, a few practical tests help.

1. How long will the crew stay? If the stop routinely runs longer than the short-term arrangement assumes, it is not short-term work.
2. Will anything stay behind? An open cut, a hot patch that cannot take traffic yet or a plate left on the road changes the job into a static worksite.
3. What speed and volume does the road carry? High-speed or busy roads often need a protection vehicle, such as a truck-mounted attenuator, and may not suit short-term arrangements at all.
4. Can approaching drivers see the work in time? Crests, curves and parked vehicles hide a stopped truck.
5. Does the training cover it? Short-term low-impact provisions come with specific training and limits. Our guide to short-term low-impact traffic management covers when the simplified approach needs review.

If any answer pushes the work beyond the simplified arrangement, stop and set up properly. In NSW, TS 05492 replaced the old Traffic Control at Work Sites manual on 25 June 2026 and added requirements on crash attenuators, end-of-queue management and temporary speed zoning, so check the current document with Transport for NSW rather than relying on how the crew has always done it.

Working the lane: positions, sight distance and the exit plan

Most patching injuries come down to where people stand and how they move. Brief these points at every pre-start and reinforce them during the shift.

Position the truck as protection

The work vehicle should sit upstream of the defect so that the crew works in its shadow, with flashing lights, arrow board or vehicle-mounted signs operating as the TGS requires. The crew loads material from the kerb side or the downstream side of the truck, never from the traffic side. Leave the roll-ahead space your procedures specify between any protection vehicle and the workers.

Check sight distance before stopping

A stopped truck just over a crest or around a curve gives approaching drivers almost no time to react. Before choosing a stopping point, consider the stopping distance for the road speed. The stopping sight distance calculator helps when planning the run. If the defect sits where sight distance is poor, use advance warning or a static set-up, or schedule the repair for lower-traffic hours.

Never cross the live lane on foot

Fetching a tool or material from the far side of the road is one of the most dangerous moments in patching. Plan the run so the crew works one side of the road at a time, and carry what is needed for the side you are on. If a defect is in the opposing lane, move the truck rather than walk across.

Keep a lookout and an exit

With a small crew, one person working head-down with a rake or compactor cannot watch traffic. Agree who watches, how they warn the crew and where everyone moves if a vehicle comes too close. Radio or a clear horn signal works better than shouting.

Look after pedestrians and riders

Patching in bicycle lanes, at kerb ramps and near bus stops affects people who are not in cars. Keep a safe path around the work, keep hot material and compaction plant clear of footpaths, and watch for cyclists squeezed between the truck and passing traffic.

Planning the run before the shift

A good patching run is planned in the office, not discovered on the road. A route sheet with the defects in a sensible order reduces U-turns, lane crossings and wasted travel.

When a run includes some static stops, count the devices those layouts need before loading, so the truck carries enough without overloading. Load material and equipment so the crew does not have to climb into the traffic side of the tray.

Reactive and after-hours patching

Storm damage and heavy rain produce dangerous potholes overnight, and callouts often happen in poor conditions: darkness, standing water, debris and drivers already struggling with visibility. Water-filled holes hide their depth, and a patch placed in a wet hole may not last.

The first job on a callout is to make the hazard safe. Depending on the road manager's procedures, that may mean warning signs, a temporary fill or a short-term closure of the affected lane until a proper repair can be made. Our guide to emergency road repairs covers making a site safe when there is no time for full planning, and when a reactive job needs to become a planned one.

Night patching needs the same care as any night work: lighting that lets the crew see without dazzling drivers, high-visibility clothing suited to night conditions, and fatigue managed for crews who may have worked a day shift before the callout.

Records that close each stop

Each patching stop should leave a short record:

• defect location and lane;
• time on site and time cleared;
• before and after photos;
• method and material used;
• arrangement used, or the TGS reference for static stops; and
• anything left unrepaired or temporary, with the action taken.

Unrepaired defects matter most. If a hole could not be fixed because of water, traffic or equipment, it must be reported and tracked, with any temporary warning devices added to the inspection list. A pothole marked "done" because the crew visited it is a liability for the road manager and a hazard for the next driver.

Common pothole patching mistakes

• Treating a saw-cut repair or long stop as mobile work.
• Stopping just past a crest because that is where the hole is.
• Walking across the road for material.
• Leaving signs in the truck for a "quick one".
• Working without a lookout on a busy road.
• Closing out a defect that was only temporarily made safe.

Next steps

Review your patching runs against the method table above, and confirm your arrangements with the road manager and the current state requirements, including Safe Work Australia guidance on traffic management at workplaces. If you run patching crews, TrafWise can hold the run sheet, SWMS sign-off and stop-by-stop records with each shift so nothing unrepaired slips through.
