Nowadays, the increasing urbanisation and the effect of climate change in cities has been a constant concern. In particular, the floods cause a significant increase in surface runoff, mostly on roads and parking areas. As an alternative to asphalt pavements, usually used in these areas, permeable pavements have been developed with Porous Asphalt (PA). These pavements allow the infiltration of water from the surface to the ground due to the high void content of the PA, thus reducing the surface runoff and increasing recharge of groundwater. Over the years, the infiltration capacity of the mixtures decreases with the clogging by sediments from the vehicles themselves and/or from the local environment. In order to mitigate this effect, a Double Layer Porous Asphalt (DLPA) was developed. This research intends to deepen the knowledge about the influence of the clogging of a DLPA, with respect to the infiltration capacity, since it is an essential theme in the pavements lifespan and that needs to be developed. This study considered different evaluation phases of the infiltration capacity with two clogging cycles (500 and 1000 g/m2). The materials used were: sand, region soil, and rubber waste. The infiltration capacity test was performed in different phases after a rainfall event of 100 mm/h with a rainfall simulator developed for this purpose. Furthermore, the permeability test with the falling head permeameter was carried out in parallel, obtaining outflow times for each clogging phase and subsequent maintenance phase. The research concluded that DLPA has a high infiltration capacity after the first clogging cycle in both performed tests. In the second clogging cycle, the results show that the infiltration decreased due to the partial filling of the pores, mainly, for the rubber-filled DLPA. The type of clogging material influences the infiltration capacity, nevertheless partially recovered after simple maintenance was performed.

如今，不断增长的城市化和城市气候变化的影响一直是人们一直关注的问题。特别是，洪水导致地表径流量显着增加，主要是在道路和停车场。作为通常在这些地区使用的沥青路面的替代品，已开发出具有多孔沥青（PA）的可渗透路面。由于PA的高孔隙率，这些路面允许水从表面渗透到地面，从而减少了表面径流并增加了地下水的补给。多年来，混合物的渗透能力随着来自车辆本身和/或当地环境的沉积物的堵塞而降低。为了减轻这种影响，开发了双层多孔沥青（DLPA）。这项研究旨在加深关于DLPA堵塞对渗透能力的影响的知识，因为它是路面寿命中必不可少的主题，需要加以发展。这项研究考虑了两个堵塞周期（500和1000 g / m2）的不同渗透能力评估阶段。所使用的材料是：沙子，区域土壤和橡胶废料。在为此目的开发的降雨模拟器之后，在100 mm / h的降雨事件之后的不同阶段进行了渗透能力测试。此外，用落头渗透仪并行进行渗透性测试，获得每个堵塞阶段和随后的维护阶段的流出时间。研究得出的结论是，在两个执行的测试中，DLPA在第一个堵塞循环后都具有较高的渗透能力。在第二个堵塞循环中，结果表明，由于孔隙的部分填充（主要是对于橡胶填充的DLPA），渗透减少了。堵塞材料的类型会影响渗透能力，但在进行简单维护后会部分恢复。
