SR bitumen sprayers

Bitumen sprayers apply binding agent for surface treatments, impregnation or specialist methods over a large width (up to over 7 m).
SR bitumen sprayers from schäfer-technic are constructed using the very latest technology. They meet current construction site requirements and support operators in the practical work.

The can process common road construction binding agents such as bitumen emulsion, bitumen, polymer bitumen and special bitumen. ADR-compliant machines can transport and process binding agents at up to 200 °C.

schäfer-technic bitumen sprayers deliver constant and precise dosing quantities and spraying results. They combine modern sensor technology and controls with ergonomic handling. This enables highly efficient work in a range of different areas. They can cover large surface areas while satisfying the very highest quality standards.

The machines have sensor-controlled automatic dosing. This means that the specified dosing quantities are ensured over the entire working width.

The computer control enables relevant technical data such as spray quantity, pressure, temperature and area to be managed. Acquired process data can be saved and retrieved using various media, including cloud and USB.

Even more options are available with schäfer-technic telematics, which creates an interactive interface between the machine and your internal software structures. Process, vehicle and job data can be viewed at any time.

The machine thus allows flexible job management and direct communication to support the operator.

Depending on the specific features, environmental data such as air temperature and humidity or even GPS co-ordinates can also be saved. The variable binding agent lateral distribution allows different spray quantities (e.g. reduced quantity in traffic lanes) to be applied in a single operation. Innovative low-pressure spraying technology reduces spray and protects the environment.

SURFACE DRESSING AND SEALING

Surface dressing involves applying a hot binding agent or bitumen emulsion, and then spreading coarse aggregate. Bond coat spraying can also be carried out with a bitumen sprayer and chippings can be added in a separate operation. Alternatively, a single combined machine can carry out both of these functions. 

As well as bitumen sprayers, schäfer-technic supplies chipping spreaders, surface dressing machines and repair trains for these kinds of applications.
