You have been invited to a ROADEX webinar of Updating the forecast model for thaw-weakening to be presented by Salla Konttinen, University of Oulu

Approximately 20 years ago, the University of Oulu and the Finnish Transport Agency collaboratively developed a predictive model for spring thaw weakening on gravel roads. This model is currently employed by the Finnish Transport Agency to generate forecasts regarding the severity of spring thaw weakening on gravel roads. These forecasts are particularly utilized in planning heavy transport during the thaw-weakening season, impacting sectors such as timber and food transportation. The predictive model is based on road and climate data and is produced in collaboration with the Finnish Meteorological Institute.

In recent years, however, the predictive model has been identified as deficient and in need of updating. The update was conducted in collaboration between the Finnish Transport Agency and the University of Oulu during the autumn of 2024. Study findings revealed deficiencies in the functionality of the predictive model. To enhance the model, three strategy models were developed, and several factors influencing the formation of thaw weakening, which require further investigation, were identified. The webinar will present the background of the thaw weakening predictive model, project results, and strategy models.

This ROADEX webinar about implementation of PEHKO results in Finland by Timo Saarenketo was held on 11/3/2024 by Timo Saarenketo from Roadscanners Oy.

You have been invited to a ROADEX webinar of Implementation of PEHKO results in Finland to be presented by Dr Timo Saarenketo from Roadscanners Oy.

Feel free to forward the invitation to anyone in your organization, and to people who you think might be interested to the webinar.

PEHKO project has been developing and testing new and innovative techniques and policies for the different processes of pavement maintenance. The aim of the project has been to improve the productivity of pavement maintenance and daily maintenance, increasing the service life of pavements and, at the same time, significantly reducing annual maintenance costs.

Now when the PEHKO project has ten years of measured survey results in Finland, it is possible to draw clear conclusions, about the main factors contributing to the increase in the life cycle costs of pavements in Finland and what should be done with them in the future. Recently written guidelines how to implement these findings has been published. Timo Saarenketo will present these guidelines.

You are invited to a ROADEX webinar on new technologies on gravel and forest road surveys to be presented by Dr Timo Saarenketo from Roadscanners Finland. Please see below the detailed description of what will be covered.

Feel free to forward the invitation to anyone in your organization, and to people who you think might be interested to the webinar.

Roughly 1/3 of the road networks in ROADEX area are gravel roads and most of the forest roads in the world are also unpaved roads. Even though their traffic volume is low, their importance to local economies is great.

Due to their nature these roads have very light structures and are exposed to seasonal changes and their condition can vary from very smooth and comfortable ride to extremely poor or even unpassable condition.

With good maintenance practices gravel and forest roads can be kept in much better shape. The problem however is that almost all the survey methods used so far have been based on subjective visual condition analysis and that is why no objective or repeatable condition has been collected from the roads. This presentation will focus on presenting some of the new techniques such as 3D accelerometers, laser scanners and GPR techniques in the analysis of functional and structural condition of gravel and forest roads.

This webinar will act also as a preview of the coming ROADEX eLearning package that will be published in January-February 2023.
