Abstract

To assess the medium-term performance of porous asphalt pavement during service and its influence on tire/pavement noise level, a seven-year continuous observation and data analysis study was conducted. Key performance indicators were measured and calculated by using automated pavement technology testing equipment. The noise levels were tested by using the on-board sound intensity (OBSI) method on three types of porous asphalt pavements (PUC-10, PAC-13, and PUC-10 + PAC-13) and one dense thin layer course (DTC) for comparison. The findings indicated that the Damage Rate (DR) and Surface Friction Coefficient (SFC) of porous asphalt pavements diminished greatly over time, while the International Roughness Index (IRI) and Rut Depth (RD) remained relatively stable. The two-layer porous asphalt pavement showed the largest noise reduction over the medium-term. Compared to DTC, the OBSI noise levels of these structures were lower by 2.09 dB, 1.53 dB, and 2.88 dB, respectively. The OBSI was found to be closely correlated with the SFC, IRI, test speed, lane, and pavement type. The RD had a notable effect on the OBSI in PUC-10 pavements. In PUC-10 + PAC-13 pavements, a significant linear relationship was observed between the OBSI and SFC. This is mainly because of the polishing of the coarse aggregates, which leads to micro-texture reduction, high frequency noise increase, and SFC decrease. This study makes a valuable contribution to understanding the laws of porous asphalt pavement performance changes and the relationship between tire/pavement noise and pavement characteristics.

调查多孔沥青的中期性能及其对轮胎/路面噪音的影响

为了评估多孔沥青路面在使用过程中的中期性能及其对轮胎/路面噪音水平的影响，我们开展了一项为期七年的连续观测和数据分析研究。使用自动路面技术测试设备对关键性能指标进行了测量和计算。使用车载声强（OBSI）方法对三种类型的多孔沥青路面（PUC-10、PAC-13 和 PUC-10 + PAC-13）和一种密实薄层路面（DTC）进行了噪声水平测试，以进行比较。研究结果表明，随着时间的推移，多孔沥青路面的损坏率（DR）和表面摩擦系数（SFC）大大降低，而国际粗糙度指数（IRI）和车辙深度（RD）则保持相对稳定。双层多孔沥青路面的中期降噪效果最好。与 DTC 相比，这些结构的 OBSI 噪音水平分别降低了 2.09 分贝、1.53 分贝和 2.88 分贝。研究发现，OBSI 与 SFC、IRI、测试速度、车道和路面类型密切相关。在 PUC-10 路面中，RD 对 OBSI 有显著影响。在 PUC-10 + PAC-13 路面中，观察到 OBSI 与 SFC 之间存在显著的线性关系。这主要是因为粗集料的抛光导致了微观纹理的减少、高频噪声的增加和 SFC 的降低。这项研究为了解多孔沥青路面性能变化规律以及轮胎/路面噪声与路面特性之间的关系做出了宝贵贡献。
