Resuspension of road dust contributes to air quality issues with resulting health impacts. Limited studies imply that porous pavements can initially mitigate PM₁₀ emissions by acting as a dust trap, but the abrasion wear generates road dust and thus accelerates the clogging processes. In addition, knowledge regarding the impact of pavement types on road dust load dynamics is limited. Road traffic noise can be mitigated using porous pavements, but the use of studded tyres increases the abrasion wear of the pavement as well as increasing the noise emission. Due to this durability problem, porous pavements are rarely used in the Nordic countries where, instead, dense pavements which are abrasion resistant are more common. Linköping municipality, in Sweden, constructed a porous pavement to mitigate road traffic noise. This led to the opportunity to investigate the temporal variation of the dust load dynamics and inherent size distributions over the winter and spring in comparison to those of an adjacent dense pavement. Results, when using the wet dust sampler (WDS) method, showed similar dust load dynamics for the dense and porous pavements. The results were also compared to previous studies using the same method on different dense pavements in Stockholm, Sweden. All locations showed a seasonal variation with higher dust loads during winter and early spring and declining loads towards summer. The size distributions were more complex for the wheel tracks at the porous pavement, having primarily properties of a mixture model compared to the simple size distributions for the dense pavement. On the other hand, the dust load and size distribution were more similar between the porous and dense pavements regarding loads and shapes, indicating a less pronounced but similar behaviour between the surfaces outside of the wheel tracks.

道路灰尘的重新悬浮会导致空气质量问题，从而对健康产生影响。有限的研究表明，多孔路面可以最初减轻_10号PM通过充当灰尘捕集器来排放，但磨损会产生道路灰尘，从而加速堵塞过程。另外，关于路面类型对道路粉尘负荷动态影响的知识是有限的。使用多孔路面可以减轻道路交通噪音，但是使用钉钉轮胎会增加路面的磨损并增加噪音排放。由于这种耐久性问题，在北欧国家很少使用多孔路面，而在这些国家中，耐磨损的致密路面更为普遍。瑞典林雪平市政府建造了多孔路面，以减轻道路交通噪音。这导致有机会研究冬季和春季与相邻密集路面的粉尘负荷动态和固有尺寸分布的时间变化。使用湿粉尘取样器（WDS）方法的结果显示，密实和多孔路面的粉尘负荷动态相似。还将结果与以前在瑞典斯德哥尔摩不同致密人行道上使用相同方法的研究进行了比较。所有地区都表现出季节性变化，冬季和初春的粉尘负荷较高，而到夏季的尘埃负荷下降。对于多孔路面上的轮迹，尺寸分布更为复杂，与致密路面上的简单尺寸分布相比，主要具有混合模型的特性。另一方面，
