AUSROAD™ Q & A

Why does Ausroad™ use the venturi delivery system and not a rotary distribution system?

The venturi delivery system that Ausroad™ uses is the most efficient way to distribute aggregate into an air stream. Now powered by PTO it has no moving parts and requires no regular maintenance or additional power source.

The Venturi increases the air velocity by 60% after it leaves the blower making the venturi system the most productive available. By reducing the speed of the blower the operator has exact control over how much aggregate is delivered via the venturi and delivery hose.

Unlike a rotary distribution system it can handle a variety of aggregates from sand to 12mm, wet and dry. It is lighter, cheaper to maintain and more effective than any other system.

With no moving parts the venturi system is the safest and most efficient system available.

Why is the boom at bumper bar level with the hose stowed in under the cab?

It is easier to blow aggregate horizontally than to try and blow aggregate several meters up and over a truck cab. This is a waste of energy and likely to cause blockages and wear on the hose. We have a low straight delivery path with less cantilevered forces and wear on equipment. There is no greasing of parts required.

With the Ausroad™ design there is no boom equipment hanging over the cab and down the side of the windshield when stowed. An over the cab set-up obstructs the driver’s visibility and is more expensive. An over the cab design also interferes with cab tilting and is difficult to service.

The Ausroad design provides extra crash protection for cab occupants. It is easy to access for maintenance and is clearly visible to the driver at all times. It is a safer set-up and ground clearance is not compromised.

The mounting of the unit to the chassis is as per truck manufacturers recommendations as approved by Hino and Isuzu Australia engineers.

With less moving parts the first Ausroad delivery boom delivered in 2000 is still in operation with its original owner (Tweed Shire Council, NSW) after 9 years of service!

Better visibility & safety
Strong construction with fibreglass filled epoxy bearings.

Why does Ausroad™ use a large diameter delivery hose?

It’s simple; with the Venturi system, Ausroad units have the highest production rates of any remote controlled unit presently available in Australia. Because of this we can use a larger diameter hose to deliver more material to the work site.

A larger diameter hose is less likely to block in any application. It also allows more material to be delivered to the patch area and a larger diameter hose makes it easier for the operator to achieve a flat finish. No speed bumps!

A wider hose means that less velocity is required to mover aggregate along it. This means less loose aggregate left at the patch area whilst maintaining high production rates and compaction.

Why Does Ausroad™ use a belt and auger system in its spreader box?

A belt and auger system allows full use of the aggregate spreader without having to tip the hopper. All speeds are adjustable from the cab to allow the correct cover rates to be applied.

Unlike the competition the Ausroad™ unit has an optimizing roller fitted to the spreader box, similar to other industrial spreaders. This allows for aggregate cover adjustment independent of ground speed. The operator can adjust spray and cover rates separately.

With the Ausroad™ belt system the hopper does not need to be tipped. Tipping the hopper cab result in stability issues and can cause safety issues in confined areas with overhead power lines and trees.

More even aggregate distribution
More control over aggregate distribution
Adjustable to aggregate sizes
No need to tip the hopper and safer
More stability

For these reasons Ausroad™ avoids having to tip the hopper.

Why does Ausroad use the ECOMAT control system?

Our control system utilises robust IFM German engineered industrial quality components. It has LED’s at every connection leading to simple fault finding and a ‘Contactless’ joystick. It utilises a flexible program giving the operator complete control over the system including job and material totals.

Ausroad is the world leader in road maintenance systems. We have designed a safe and cost effective unit specifically for Australian conditions.

Units can be retro fitted with our latest technological developments.

Is the Jetmaster Unit easier to use than other road patching / repair machines?

Yes, because operators are able to blow all debris from the potholes, patch large areas such as edge breaks and sheet patches more efficiently and "clean up" is easier at the end of the day.

The Jetmaster remote control unit allows road repairing from the comfort and safety of the truck cab.

Is the Jetmaster Unit noisier that other road patching / repair machines?

The Jetmaster Unit satisfies all current Australian legal requirements. When using the Jetmaster remote control unit the operator / driver is inside the truck cab where measured noise levels are 1db higher than truck alone.

Is material wastage a problem with the Jetmaster Unit?

No, even with new operators material is not wasted due to the ability to slow production rate to suit operator and situation.

How do the operating costs of the Jetmaster Unit compare to those of other blower type patching machines?

Very well. In fact, operating costs are lower than other machines. This is because of the efficiency of the Jetmaster's Venturi, the conveyor belt distribution system, the larger volumes of material produced with a large diameter hose, the reduction in maintenance or down time of the distributing system and the ability of the Jetmaster to use relatively low cost materials mixed on the spot - no wastage.

Why is the Jetmaster Unit more productive than other patching machines?

The fully pneumatic all air venturi system allows greater volumes of material to be processed than can be achieved with other machines. The large diameter hose and nozzle allow this material to be placed at high speed and volume.

Can the Jetmaster Unit be used in cold conditions?

Jetmasters are operating in the cold. European conditions and the heat and humidity of the South Pacific Islands. With the use of the heat exchanger cold conditions pose no problems for the Jetmaster Unit.

Can the Jetmaster Unit be used in wet conditions?

Yes - providing it is not raining heavily at the time of repairing. Rain immediately before the repair work poses no problems.
