Abstract [en]

To analyze tire-road contact characteristics and the effect of the contact on pavement skid resistance, the two-dimensional discrete data of the road texture profile was measured using the road surface tester, and the enveloped profile was calculated using the indentor method in MATLAB. Based on the enveloped profile, texture parameters such as mean profile depth (MPD), macro texture indices calculated with texture level (LMa), and mega texture indices calculated with texture level (LMe) were calculated, and comparisons were made between these and the original profile. Then, the correlation between the friction value (longitudinal friction coefficient, LFC), and the calculated texture parameters considering the original and enveloped texture profiles were analyzed. The results show that the calculated texture parameters with the enveloped profile have a high correlation with those calculated with the original profile, the determination coefficient R2 is higher than 0.85. The calculated MPD value with the enveloped profile shows a significant decrease, compared to that calculated with the original profile, and the larger the original MPD value, the greater the decrease in the envelope contour MPD value. The calculated texture level indices with the enveloped profile are also reduced when compared to the original. The decline rate of LMa is about 10% higher than LMe. The variable parameter S from the indentor method has a significant impact on the enveloped texture parameters, texture parameters with a smaller S show a higher decline. The determination coefficients between friction value LFC and calculated pavement texture parameters with the enveloped profile improved significantly compared with the original, with an increase of approximately 35% in MPD and 23% in LMa. The research results can provide a reference for studying the effect of tire-road contact characteristics on road performance. 2 tabs, 14 figs, 27 refs.
