This investigation focused on the effect of nanoparticles on microstructural surface characteristics, abrasion, and skid resistance of concrete pavements. Firstly, the percentage of optimal replacement of nanoparticles was determined. In the second part, the nano-modified concrete similar to mortars in terms of water-to-cement and sand-to-cement ratio were made to study the abrasion resistance and British pendulum number (BPN) as skid resistance property. Mercury intrusion porosimetry (MIP), X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM) were applied to accurately evaluate the microstructural properties. Concerning concrete containing different nanoparticles, nano-montmorillonite yielded the most considerable improvement in abrasion resistance (about 23%). By examining the MIP results, a good correlation was observed between the volume of the large pores plus the average pore size and the volume reduction in the abrasion test. By comparing the effect of nanoparticles on improving the skid resistance under wet and dry conditions, it was found that the samples containing nanoparticles in dry conditions generated more significant improvements (about 20%) compared with the wet conditions (about 7%). The results of the AFM test revealed that improvement in samples containing nanoparticles was because of increased surface roughness and enhanced surface adhesion due to Van Der Waals forces.

这项研究的重点是纳米颗粒对混凝土路面的微观结构表面特性，耐磨性和防滑性的影响。首先，确定纳米颗粒的最佳置换百分比。在第二部分中，制备了类似于砂浆的水灰比和砂灰比的纳米改性混凝土，以研究其耐磨性和英国摆数（BPN）作为防滑性能。应用汞侵入孔隙率法（MIP），X射线衍射（XRD），扫描电子显微镜（SEM）和原子力显微镜（AFM）来准确评估显微组织性能。关于包含不同纳米颗粒的混凝土，纳米蒙脱石在耐磨性方面有最显着的提高（约23％）。通过检查MIP结果，在磨损试验中，观察到大孔的体积加上平均孔径与体积减少之间具有良好的相关性。通过比较纳米颗粒在湿和干条件下改善防滑性能的效果，发现与干燥条件（约7％）相比，在干燥条件下含有纳米颗粒的样品产生了更大的改善（约20％）。AFM测试的结果表明，含纳米颗粒的样品的改进是由于范德华力增加了表面粗糙度并增强了表面附着力。发现在干燥条件下含有纳米颗粒的样品比在潮湿条件下（约7％）产生了更大的改善（约20％）。AFM测试的结果表明，含纳米颗粒的样品的改进是由于范德华力增加了表面粗糙度并增强了表面附着力。发现在干燥条件下含有纳米颗粒的样品比在潮湿条件下（约7％）产生了更大的改善（约20％）。AFM测试的结果表明，含纳米颗粒的样品的改进是由于范德华力提高了表面粗糙度并增强了表面附着力。
