Mobile batch-type plants are the best solution for producing asphaltmixes near road building sites and when the mixes are subject tostringent quality regulations, especially in terms of the grading curve.Their mobility makes them highly versatile and so, when it is necessaryto step-up local production, they can easily move sites.These are the underlying reasons that have led to the creation ofROADSTAR.

R O A D S TA R

Mobility and performance

The idea behind ROADSTAR is to optimize transfer and assembly operations,without compromising the asphalt mix quality in any way. Installation proceduresare also made easier.

Ergonomics and accessibility

All areas of the user-friendly plant are easily

accessible in total safety, during both production

and maintenance.

Material metering quality

All materials (aggregates, fines, bitumen) are

metered into their own separate weighing hoppers,

just like in traditional stationary plants.

Versatile production

The mobile hot bin guarantees uninterrupted

homogeneous mixes, reducing the number of

trucks needed to service the work site.

Energy saving

Producing the asphalt mix near the work site

means a reduction in the heating of the materials

and likewise in energy consumption.

Optimum transport and quick assembly

The component parts are mounted on axles for

easy transport. Factory pre-wiring of plug and

socket cables cuts down on installation time.

Reduced cement foundations

Self-supporting steel foundations mean the plant

can be erected on stabilized ground (2.5 kg/cm2),

without having to build cement foundations. This

also makes transfer operations easy.

Recovered fines and imported filler:

� Basic model: the hot recovered fines (a) and any cold

imported filler (b) are carried on the vertical auger (2)

to the fines scale-mounted weighing hopper

� Alternative: separate metering of hot recovered fines

and imported filler

Dryer drum

� Specially designed flights to maximize heat exchange

� Recycling ring (optional)

� Powered by friction drives (RS 2700)

� Mono-block burner, suitable for all fuel types

Mixer

� Double shaft and twin motor reducers

� Same mixing concept as a stationary plant (seal,

durability, etc.)

Material metering

Aggregates, fines and bitumen are all weighed in their

own weigh hopper to guarantee metering accuracy.

Vibrating screen

� totally bolted frame

� external control device

� 4 sizes on 2 decks (on RS 1300 / RS 1500 / RS 1800)

� 4 or 5 sizes on 3 1/2 and 4 1/2 decks (on RS 2700)

� integrated depression system

� 24 hours factory screen testing

Under screen bins

� 4 or 5 bins from 13 to 18 tons, depending on model

� by-pass into sand hopper

Control cabin

� Electric power display

� Pre-wired cables with plugs and sockets for rapid

connection to each component

� CYBERTRONIC production management system

� EXCEL® exportable production filing records

S y n t h e s i s

Optionals

A wide range of components and accessories have been designed to enhancemobility.

Highly mobile

A set of mechanical or hydraulic lifters can be fitted to

the bag filter unit to assist positioning.

Also cold feeders, bitumen/fuel storage tanks

can be fitted with hydraulic lifters.

Transport

Upon request, trailers can be fitted with suspensions

capable of transporting up to 70 km/h.

Kit for special products and additives

Plants may be adapted for use with special additives

(fibres, colourants, polymers).

Mobile modules
