研究了积砂对沥青路面抗滑性能的影响。许多学者对常规沥青路面的抗滑性能进行了研究。然而，目前对沙漠道路在积沙条件下的抗滑性能的研究还比较缺乏。本研究使用AC-13和AC-16沥青混合料。用摆式摩擦系数仪测量了不同积沙量下的英国摆数(BPn)，并使用Ames工程纹理扫描仪获得了不同的积沙量。以沥青混合料的质构指数为指标，研究了不同积沙量下沥青路面的宏观和微观质构，并通过灰色关联分析得出了不同粒径对BPN的影响程度。试验结果表明，风积沙的存在对沥青路面的宏观和微观结构有显著影响，会导致沥青路面的抗滑性能下降。此外，路面纹理指数与BPN之间存在明显的线性正相关。研究成果可为沙漠公路的设计和养护提供参考和参考。
The influence of sand accumulation on the skid resistance of asphalt pavement was studied. Many scholars have researched the anti-skid performance of conventional asphalt pavements. However, there is a lack of research on the anti-skid performance of desert roads under the condition of sand accumulation. In this study, AC-13 and AC-16 asphalt mixtures were used. The British Pendulum Number (BPN) under different sand accumulations was measured with a pendulum friction coefficient meter, and the Ames engineering texture scanner was used to obtain different sand accumulations. The texture index of asphalt mixture was used to study the macro and micro texture of asphalt pavement under different amounts of sand accumulation, and the degree of influence of different particle sizes on BPN was obtained through gray correlation analysis. The test results show that the presence of aeolian sand has a significant impact on the macro and micro texture of the asphalt pavement and will cause the anti-skid performance to decrease. Moreover, there is an apparent positive linear correlation between the road surface texture index and BPN. The research results may provide reference and reference for the design and maintenance of desert highways.
