Title:

Study of the Snow Pavement Interface: GELCRO project

Abstract:

In the GELCRO project, we developed a model enabling forecasting of the condition of a road surface before snow falls and monitoring of evolution following snowfall. To develop specific knowledge on snow/pavement interface, and experimental site was selected. Snowfalls and highly changeable weather were the characteristics determining this selection. The site is equipped with six experimental sections of road representing widely used surfaces in France. Various probes are inserted in these sections. Manual measurements are made during or just after a snowfall and snow/road composite samples are taken. An original technique has been developed in a cold laboratory and enables the observation of the snow/pavement interfaces. Complete observation and and analysis of different snowing events should help us to better understand snow pavement interface and to make a parameterization of typical situations. These results will be used for future development and validation of the GELCRO model.
