ThermoMAT
ecological and economic benefits
The ThermoMAT®, an economic and ecologic investment into road and traffic safety.!
Road surface temperature: a decisive factor
Traditional spreading intervention requires road maintenance personnel to estimate and manually adjust the necessary spreading density for the meteorological and road surface conditions at
the given moment. Permanent changes in road surface temperatures e.g. because of:
Bridges or superstructures
Changes of road surfaces
Hollows
Watercourses
Forests
make it practically impossible to react manually to all these changes. That is why, to be safe, thousands more tons of salt than required are spread each year, thus raising the cost of winter maintenance and increasing the environmental impact.
How it works
Before starting the intervention maintenance personnel enter the road condition in accordance with
the table below. There is a choice between 4 freeze stages, from hoarfrost to ice covered road surface.
For manual adjustments there is a 5th stage.

During operation the ThermoMAT® measures the road surface temperature continuously, several times
per second, thus reflecting shortest reaction times.

Using the ThermoMAT® only the freeze stage selection is executed
manually, all spread density regulations are automatically performed by ThermoMAT® which continually adjusts to match the immediate conditions. Hydraulic adjustment is performed within milliseconds using proportional flow-regulation valves. In this way,
winter maintenance not only becomes more economic and ecological, but also is safer, both for road users - due to optimally spread
roads, and also for maintenance personnel - due to significantly reduced costs.
The spreading freeze stage diagram visualizes the dependency of
road surface temperature in different spreading freeze stages.
Boschung’s new spreaders with intelligent Optiwet® technology
lead the way for the achievement of precise, to-the-gram, spreading densities.
Save up to 30% of thawing agent
Practical tests over several years haven proven that the use of ThermoMAT® typically
saves up to 30% of thawing agents.
These savings result not only in positive effects to the environment but also to the
economic situation. Based on an average winter, the costs using of ThermoMAT®
with wet salt on roads can be recovered within 2-3 years, presuming an average hopper size and an average brine density of 20%.
In use on airports with higher thawing agent costs, the cost recovery time is even
shorter.
