Abstract

This study explores the mechanical properties of porous-asphalt pavement, focusing on the influence of various polymers (elastomeric and reactive elastomeric terpolymers) and different aggregate compositions. Two aggregates were utilized: one is exclusively limestone-based and the other is a blend of limestone and basalt aggregates. The research findings unveiled that mixtures containing the conventional bitumen failed to meet the Cantabro loss-test criterion required for porous asphalt, necessitating a maximum threshold of 20%. In contrast, asphalt mixtures modified with polymers exhibited notably superior performance, particularly in terms of permeability, Cantabro loss and the ratio of indirect tensile strength. These results underscore the significant impact of polymer modification on enhancing the crucial mechanical properties of porous asphalt. Therefore, the study suggests the adoption of polymer-modified asphalt as a viable strategy to improve pavement longevity and overall performance, promoting its use for sustainable and durable infrastructure. Keywords: Porous asphalt, Permeability, Modified porous asphalt, Porous-asphalt design, Polymer modification, Cantabro loss.

环保型透水路面的机械特性：增强型多孔沥青

本研究探讨了多孔沥青路面的机械性能，重点是各种聚合物（弹性体和反应弹性体三元共聚物）和不同集料成分的影响。研究使用了两种集料：一种是完全基于石灰石的集料，另一种是石灰石和玄武岩混合集料。研究结果表明，含有传统沥青的混合料无法达到多孔沥青所需的坎塔布罗损耗测试标准，因此必须达到 20% 的最大临界值。相比之下，使用聚合物改性的沥青混合物则表现出明显的优越性能，尤其是在渗透性、Cantabro 损失和间接抗拉强度比率方面。这些结果凸显了聚合物改性对提高多孔沥青关键机械性能的重要影响。因此，研究建议采用聚合物改性沥青作为提高路面寿命和整体性能的可行策略，促进其在可持续耐用基础设施中的应用。关键词多孔沥青渗透性改性多孔沥青多孔沥青设计聚合物改性康塔布罗损失
