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.
Abstract
In view of the importance of the pavement microstructure to the skid resistance of the pave-ment,8 curves of the key sieve holes were selected to study the sample forming.The correlation be-tween texture parameters and skid resistance index was studied by means of AMES texture scanner,3 D reconstruction technique of MATLAB software and box counting method of fractal theory.The re-sults show that there is a good linear relationship between the surface morphology and the skid resist-ance of asphalt pavement in the 3 D model reconstructed by MATLAB software with high precision re-storing of the surface morphology of asphalt pavement,and it provides a strong guarantee for predic-ting the long-term skid resistance of pavement.
