THE EFFECT OF SURFACE GEOMETRY ON THE LUBRICATED SLIDING FRICTION AND POLISHING OF ROADSTONES

A MEANS OF STUDYING THE FINE THREE-DIMENSIONAL SURFACE GEOMETRY OF ROADSTONES AND ITS USE IN DETERMINING A SUITABLE CHARACTERIZATION OF THE LUBRICATED SKID RESISTANCE PROPERTIES OF ROADSTONES ON RUBBER IS DESCRIBED. THE FRICTION PREDICTED BY A THEORETICALLY DETERMINED CHARACTERIZATION IS COMPARED WITH FRICTION TESTS ON TEN ROADSTONES. THE NATURE OF POLISHING AND OF THIN FILM LUBRICATION IS ALSO DISCUSSED. REFERENCE IS MADE TO THE USE OF STEREOPHOTOS BY THE ROAD RESEARCH LABORATORY FOR THE MEASUREMENT OF ROAD SURFACE PROFILE IN SKID RESISTANCE STUDIES. /RRL/
