ViaFriction

ViaFriction ViaFriction is a one-wheel trailer, measuring the degree of friction of the pavement surface.  ViaFriction is developed for both winter and summer conditions. A unique measuring technology has been developed for ViaFriction, continuously measuring the real friction in between the tire and the road surface.  The technology gives stable results in various conditions, reducing the need for calibrations. ViaFriction has few moving parts.  This ensures that the unit is almost maintenance free.  ViaFriction is using an electric break in order to break the measuring wheel.  The generated power is used  to keep  the unit free from snow and ice  during  winter  conditions.

ViaFriction Measurements during summer conditions requires a water film in between the road surface and the test tire.  ViaFriction units delivered for both summer and winter conditions will include a system to apply the water film. The watering system includes a water tank on a trailer or in the trunk of the vehicle. ViaFriction will run freely behind the vehicle during transport distances, but the unit may also be fitted with a device lifting the unit off the road.

Recorder (ViaFriction)

ViaPlot Desktop (ViaFriction) Testen består i å måle en strekning 2 ganger med hastighet på 60 km/t. Målestrekning er på RV31 fra skilt mot Reinslakteriet til snuplass før Botne Camping. Dette er noen mil utenfor Røros. Målingen gjøres i retning Sverige. Veien har noen få flekker med bar asfalt. Teststrekningen er en lang bakke nedover og det er tåke som legger seg på veien. Valg av felt og HP er ikke korrekt på måleseriene.

Digital Photo System (ViaPhoto)

Digital Photo System (ViaPhoto) ViaTech’s Digital Photo System is mainly used for inspection and maintenance planning of road, rails and airport runways. Maintenance planning is based on the information gathered about pavement surface and vegetation growth as well as the status of such factors as all signs, markings and safety barriers. The Digital Photo System is also highly suitable to document sub suppliers’ maintenance work and the drivers’ view distance. The Digital Photo System automatically produces high quality digital images from a vehicle of your choice. All pictures are marked with information such as road data and time.

Recorder (ViaPhoto) ViaPhoto opptaker

Digital Photo System (ViaPhoto) ViaPhoto has the following characteristics: The recommended minimum time between pictures is 0,5 seconds. The normal shutter time outdoors is 1/5000 sec. At 80 km/h the vehicle travels only 5 mm while the picture is taken, ensuring that even the smallest details are visible. In tunnels the normal shutter time is 1/25 sec allowing sufficient information to be recorded. This precision is available with normal dipped headlights, which means no disruption to the flow of traffic. All elements in the picture can be measured. The horizontal and vertical ruler resolution is 1cm at a distance of 10 m.
