摘　　要：鉴于道面微观构造对于道面抗滑性能的重要性,文中选取变化关键筛孔的8条曲线,进行试样成型研究。借助纹理激光仪AMES进行表观纹理提取,运用MATLAB软件三维重构技术,并使用分形理论的盒子计数法,研究纹理参数与抗滑性能指标的相关性。研究表明,MATLAB软件重构三维模型高精度还原沥青道面的表观形貌,道面构造参数与抗滑性能之间具有良好的线性关系,可为后续预测道面长期抗滑性提供保障。In view of the importance of the pavement microstructure to the skid resistance of the pavement,8 curves of the key sieve holes were selected to study the sample forming.The correlation between texture parameters and skid resistance index was studied by means of AMES texture scanner,3D reconstruction technique of MATLAB software and box counting method of fractal theory.The results show that there is a good linear relationship between the surface morphology and the skid resistance of asphalt pavement in the 3D model reconstructed by MATLAB software with high precision restoring of the surface morphology of asphalt pavement,and it provides a strong guarantee for predicting the long-term skid resistance of pavement.
