SEASONAL VARIATIONS IN THE ADHESION OF PAVEMENTS MEASURED WITH THE SCRIM APPARATUS

VARIATIONS SAISONNIERES DE L'ADHERENCE DES CHAUSSEES MESUREE PAR L'APPAREIL SCRIM

The SCRIM (Sideways force Coefficient Routine Investigation Machine) developed in Great Britain has been used in France since 1974 for the examination of the skid-resistance properties of the French highway network. This machine continuously measures, at 60 km/h, the sideways force coefficient (SFC) of a bald tire on a wet pavement. The article describes the studies conducted in order to better determine SFC variations due to factors which are not easily controlled. It draws practical conclusions with regard to the operational utilization of the measurements within the framework of the scheduling of pavement maintenance operations. The factors considered are the following: - position of machine in cross section, - horizontal alignment of road, - wear of measurement tire, - climatic influences. Experiments make use of several methods, including the processing of a large number of values (measurements distributed over 8 years) by computer using statistical methods.
