The Roadmaster® is the market leading Spray Injection patching machine.

The Roadmaster® is the market leading Spray Injection Patching machine. It prepares the site and delivers a computer calibrated mixture of aggregate and binder directly into the pothole or road defect under high velocity, ensuring a cost effective, reliable solution to problematic road maintenance issues.

The Roadmaster® is a one man operation, ensuring high levels of productivity and greatly reduced risk to operators. No body is exposed to traffic hazards, dust, fumes, noise, weather or bitumen. The sole Operator sits in the comfort of an air conditioned cab controlling everything at the touch of a button.

Unique to the Roadmaster® is the PLC (Programmable Logical Computer) control system. The PLC ensures that the application rates can be pre-set, allowing for the binder and aggregate mix to be calibrated, ensuring that the material is always laid within specification and at the correct application rate. This consistency guarantees you lasting results and best value in road defect repair every time. The Operator can store settings for the recommended application rates of different aggregate and bitumen emulsion combinations, reducing the requirement for manual input from the operator and potential human error.

Repair Types Possible with the Roadmaster®

Pothole Repair

Remove all water and debris with high pressure air jet. Tack coat the area. Build up the patch with a calibrated mixtuere of emulsion and aggregrate and top off with dry chips.

Preventative Seal On Cracked Area

Priming and application of layers of coated chips will raise and strengthen the surface and prevent water ingress. The finished patch will normally have rectangular shape with well defined edges.

Build Up Broken Edges

An effective and inexpensive way to reinstate ragged and broken carriageway edges.

Pre-surface Dress Work

Depressions can be raised, cracks filled and stripped areas reinstated, prior to surface dressing for a fraction of the cost of conventional means.


Small areas can be very effectively surfaced using the Roadmaster® System, i.e. areas which might be disproportionately expensive using conventional surface dress systems. Coverage of up to 1500 msq per day has been recorded.

Intricate repairs

Detailed, intriciate repairs in difficult to reach areas; due to proximity to obstacles such as kerbs are no problem for a Roadmaster®.

Users have achieved a financial saving of up to 80% when compared with conventional repair methods.

The Roadmaster® has been designed with this in mind and has the following key safety features:

Operated from the safety of the chassis cab – There is no need for an operative to stand on a live carriageway to carry out a road repair 

There is no manual or material handling on site and no direct environmental exposure. 

The Roadmaster is fitted with manoeuvring sensors, reversing alarms, rear cameras and can also be fitted with a driver assist function. 

An LED arrow board can also be mounted on the rear of the Roadmaster enabling the operation to carry out as independent mobile works.

As the SIP process fills the existing road defect void without the requirement for excavation there is a reduced requirement for new material. 

Can prevent early stages of deterioration such as fretting and cracked surfaces which ultimately results in more cost-effective programming of any network.


The one man, one truck operation, literally takes auxiliary vehicles off the road. The Spray Injection patching cleans the existing area, without the need for cutting out of large pieces of road surrounding the defect.

The computer calibration of aggregate ensures no unnecessary material is used in the fix.

The Roadmaster also offers market leading data capture, the Centaur Light. This provides local authorities and term maintenance contractors with real time information on the operation of every Roadmaster on the road.

Not only is this useful from a reporting perspective but also as a means to document in detail the before and after of each fix. This verifiable data has proved its value time and time again in relation to insurance queries, quotes and claims.
