The pavement skid resistance is of vital importance for road safety and maintenance. The existing studies mainly calculates various parameters of pavement texture to evaluate the skid resistance. However, most researchers mainly calculate the whole texture parameters, but rarely consider which part of the texture is actually involved in the friction. This paper studies the measurement and calculation of the tire-pavement contact area and its influence on the skid resistance prediction. In this study, we proposed a set of methods to predict the rubber-contacted pavement area percentage and to extract the rubber-contacted texture. Besides, the skid resistance prediction models based on high-resolution three-dimensional (3D) surface data of the whole and the contacted texture are built and compared. The results show that when the rubber-contacted percentage is set at 20% or ̃% (the predicted percentages), the accuracy of the prediction model is higher. It is demonstrated that the performance of the skid resistance prediction will be improved by extracting the contacted texture. Also, the amount of data can be considerably reduced, which will effectively relieves computational cost.

路面抗滑性能对道路安全和养护至关重要。现有研究主要通过计算路面纹理的各种参数来评价路面抗滑性能。然而，大多数研究人员主要计算整个纹理参数，而很少考虑纹理的哪一部分实际参与了摩擦。本文研究了轮胎与路面接触面积的测量和计算及其对防滑性预测的影响。在这项研究中，我们提出了一组方法来预测橡胶接触路面面积百分比和提取橡胶接触纹理。此外，建立并比较了基于整体和接触纹理的高分辨率三维（3D）表面数据的防滑预测模型。结果表明，当橡胶接触百分比设置为20%或̃%（预测百分比）时，预测模型的准确性更高。结果表明，通过提取接触纹理将提高抗滑性预测的性能。此外，数据量可以大大减少，这将有效地减轻计算成本。
