Fast and economical with micro surfacing

SM from schäfer-technic

Micro surfacing differs from conventional working with asphalt in a number of ways. Application is one of them. Because application is significantly more convenient, the method is more efficient, more environmentally friendly and safer than application of conventional asphalt, but still delivers the same durability.

These ground breaking results are based on decades of research by companies that have continuously developed and perfected the product since it was first used. As a result, it meets the highest quality standards.

With schäfer-technic SM micro surfacing machines you can create an asphalt mixture with consistent precision and lay it directly on the road surface - with just one machine, directly on the construction site.

When designing the machines, we rely on proven components and metering systems on the one hand and on continuous improvement on the other.
This means your machines will always meet the very latest technical requirements for practical operation on the building site and will integrate smoothly into your efficient working processes.

The components are fed into the twin-shaft mixer in the relevant quantity and mixed homogeneously. In a second step, mineral is added using a feeder conveyor belt and solid additive using a feeder screw. The liquid components such as bitumen emulsion, water and liquid additive are pumped, with the quantities configured using the metering control.

Thanks to a huge range of different equipment options, micro surfacing machines from schäfer-technic are ideal for any requirement. Additives such as lime, lime milk, fibres, colourless special emulsions and colour pigments can be incorporated. The range also includes special pavers, communication software with process data acquisition and additional adaptations.

Our protected bond coat sprayer offers a totally new overall concept. Application and layer bonding are consistently of a higher quality.

The micro surfacing machines from schäfer-technic are high performance laying machines. Despite their relatively small external dimensions they achieve maximum productivity.

The machines support you in achieving your qualitative and quantitative objectives.

Micro surfacing machines in action

MICRO SURFACING

The micro surfacing method enables road surfaces to be quickly covered with a high quality asphalt mixture. Construction sites can normally be opened to traffic again after around 20 minutes.

As well as micro surfacing machines, schäfer-technic also offers the Mini-Mix in various versions and configurations for producing and laying high quality asphalt mixtures.
