Thermography

Why have a road thermography study done?

We do road and highway thermography studies to:

  • Understand and visualize the thermal heterogeneity on a road axis or spreading circuit.
  • Identify and visualize specific points on a network.
  • Adapt your road treatment policy. More specifically the higher priority road segments, as well as the creation of new road circuits.
  • Décider objectivement de l’implantation des stations routières : points froids, zones représentatives.
  • Increase the quality of your network’s forecasts.

To optimize human and economic means while increasing the network’s practicability and user security.

Ciel dégagé et vent calme à faible

The relative temperature of a road segment varies with radiation conditions.

The thermal heterogeneity depends on radiation conditions; minimally under a covered sky and windy conditions, optimally under a clear sky with little to no wind.

In what conditions can a road thermography study be done?

We do a road thermography study under the following conditions:

  • In winter
    • Faible rayonnement solaire, nuits longues, sous-sol froid
  • Dormant vegetation
    • Few or no leaves in the trees
  • In the second part of the night
    • Between 00 and 06 am UTC
  • On a dry network
  • Under a clear sky
    • Optimal ‘outgoing’ radiation
  • With light winds
    • Little or no turbulence
