Seasonal Change Management

Seasonal changes and freeze-thaw process and the damage they cause are the most significant factor affecting the road condition of northern cold climate road networks in Europe, Asia and North America.  It can be stated that 60-80 % of the distresses appeared during the spring when the road is weakest.  Since the company´s establishment in 1998, Roadscanners has worked in several projects with the goal to develop techniques and systems for better road condition management  during the spring thaw weakening period. These have been designed  in such a way that they have minimized the impact of transportation problems on local livelihoods without destroying road structures or reducing the service level of the road for the rest of the year. Seasonal change management is always a combination of improved maintenance standards, focused rehabilitation design on the weakest road sections, real time monitoring of road structures and new computer controlled tyre pressure techniques.

Roadscanners has, since 2000, offered Percostation services in Finland, Sweden and in Scotland for monitoring seasonal changes, making forecast for spring thaw weakening and providing weekly reports on the current status of road structure and subgrade moisture content and the risk for permanent deformations under heavy axle loading.
