SODIUM CHLORIDE--A POTENTIAL CAUSE OF SLIPPERY ACCIDENTS

It can be expected that sodium chloride dilhydrate will form on winter roads under certain conditions when temperatures fall below a given level. In order to clarify whether or not the formation of hydrohalite on the pavement can explain the phenomenon of ice appearing to be resistant to road salt, a comparative study has been made on a number of different surfaces measuring friction index. The friction measurements were performed with a portable skid resistance tester. Is therefore possible that the formation of hydrohalite contributes to accidents on slippery roads.
