THE RELATION BETWEEN SURFACE TEXTURE OF ROADS AND FRICTION AND ABRASION OF TYRE TREAD RUBBER

Laboratory tests on artificial road surfaces have shown that tyre tread rubber abrasion increases as the participating scales of texture increase in fineness and increase in ruggedness (average abolute slope). Abrasion also increases as the damping factor, the load and the speed of sliding of the rubber increase. These results were predicted previously (Yandell 1971b). The test results show that for the sliding speeds occurring on roads the removal of a certain range of fine texture can reduce tyre abrasion by 40 per cent but reduce friction by only 5 per cent. Further experimental support for the theory of hysteretic sliding friction together with evidence of an additional form of friction -- that originating in cohesive shear in the rubber -- are presented in this paper. /Author/
