INCREASED STOPPING DISTANCES DUE TO ICE ON BRAKE BLOCKS

A theory is proposed which predicts increased stopping distances due to ice on brake blocks by assuming that an initial low brake friction is maintained until the ice layer is melted by frictional heating. The friction then becomes that of the dry block. Reasonable agreement is obtained with Winter stopping distances published by O.R.E. which reveal that all types of block, including cast iron, are similary affected by pre-formed ice layers.
