A STUDY OF THE EFFECT OF TEMPERATURE ON PAVEMENT FRICTION

This report is a comprehensive evaluation of temperature effects in sliding friction, in particular as they relate to tyre/pavement interaction for full-scale road testers and slider/surface interaction using the British portable skid- resistance tester. It is shown from experiments conducted in the laboratories at pottery road that a correction of approximately 0.69 units of skid-resistance as measured with the portable tester (or 0.0069 units of sliding friction coefficient) per degree centigrade of interface temperature can be applied to scrim test results, to compensate for temperatures which deviate from some standard reference (usually 21 degrees C). This permits utilization of the scrim machine on a year-round basis-it is only necessary to estimate tyre-road interface temperature at each time of year, so that the effect of seasonal variations on skidding resistance are eliminated. /TRRL/
